Both dharma teachers (Yogi Prabodha Jnana and Yogini Abhaya Devi) are yogis that went for 9 years retreat and trained in the Nyingma lineage.
Their main practice is Dzogchen. They went for 9 years retreat and was encouraged by their gurus to teach. Their gurus are Kyabje Penor Rinpoche, Kyabje Karma Kuchen Rinpoche and the three Khenchens of Namdroling Monastery. 
Here's the article "Bodhidharma Teachings":
                    
                        

In this second part of the trilogy on Bodhidharma, let us go deeper 
into his teachings, including the two methods Bodhidharma taught for 
entering the Way of Awakening.  We shall also see how Bodhidharma’s 
teachings fit within the broader context of various Mahayana methods.

 Bodhidharma taught through silence and words, and through resting 
and movement. Sometimes he just sat silent and dissolved the conceptual 
proliferations of seekers in that silence. Sometimes, he used abrupt and
 loud words and expressions to totally shift the mindset of disciples 
and to bring to dust their  frames of reference. In resting like a 
mountain, gazing at the empty wall of mind’s nature, he showed how the 
mind of dualities and conceptual proliferations comes to rest in the 
basic space of the perception and the perceived.
 In moving like a wild goose spreading its wings, he showed how the 
perception and the perceived never harm the silence of the basic space.
The View from the Summit
In the view of awakening, as expressed by the Buddha in the 
Prajna-paramita-sutras, Lankavatara-sutra, and so on, the perception and
 the perceived are seen to be unborn, without a beginning. The 
perception and the perceived have never ever arisen as independent 
realities separate from the basic space of all phenomenal arising. 
 Realizing this principle cannot be the result of seeking. It is rather 
like seeing the entire landscape from the top of a high summit by 
resting and not seeking. All teachings of the Buddha, and particularly 
Mahayana Sutras, skillfully take disciples to this summit. Bodhidharma’s
 teachings are in essence no different from this.
There are broadly two approaches to arrive at the summit. One is that
 of the Nalanda masters. It involves elaborate study and then using the 
sword of prajna (understanding) through logical reasoning and 
contemplations to cut one’s conceptual proliferation branch by branch. 
As the thoughts that proliferates with dualistic conceptions are 
gradually eliminated with the sword of prajna, one reaches the summit of
 non-conceptual view that is beyond seeking. The other approach is that 
of close master-disciple relationship. In this case, by following the 
skillful personal instructions of a master, the disciple quickly gains a
 glimpse into that non-conceptual view by instantaneously cutting 
through whatever obscured true seeing. Then, the disciple trains to rest
 at the summit of that non-conceptual view of the basic space, without 
taking recourse to elaborate reasoning and logic. Bodhidharma emphasized
 the latter.
Bodhidharma’s teachings, matching with his time, made sure that the 
skillful means of realizing the vast expanse of one’s own mind does not 
turn into mere religiosity. Buddha-dharma was already very popular by 
then and people were turning it into religious systems. So, for 
Bodhidharma, it was important to dismantle the religiosity to show the 
true meaning of the Buddha’s teachings.
He always emphasized that the purpose of practicing Dharma should be 
to tame and transform mind, and all the more to realize Buddhahood that 
is in one’s nature beyond all seeking and rejecting. He repeatedly made 
it clear that there is no use doing elaborate practices in a religious 
way if you miss this real meaning and purpose.
Finding the Buddha
Bodhidharma said,
To find a Buddha, you have to see your nature.
Whoever sees one’s own nature is a Buddha.
Invoking Buddhas, reciting Sutras, 
Making offerings, and keeping precepts 
Are all useless if you don’t see your nature.
Invoking Buddhas results in feeling blessed; 
Reciting Sutras results in a good memory;
Keeping precepts results in a good rebirth;
And making offering results in good karma; 
Yet, none of those result in finding the Buddha.

To
 find a Buddha all you have to do is to see your own nature. Your own 
true nature is no different from that of a fully awakened Buddha. If you
 don’t see your nature, and instead run around all day looking 
elsewhere, you’ll never find a Buddha. In fact, there’s nothing to find.
 There is no Buddha to seek elsewhere. Just recognize your own innate 
potential and let it naturally flourish. There, you find the true 
Buddha. Invoking Buddhas, reciting Sutras, making offerings, keeping 
precepts and various other such activities are only to create conditions
 to get closer to that recognition and to make it easier for it to 
flourish. But, if you go on looking outwardly to see results from such 
actions without turning attention towards your own mind, then you won’t 
find a Buddha. The best one can gain by performing such acts religiously
 is some good karma, good memory, good rebirth, and feeling blessed, 
keeping the hope alive, but never Buddhahood!
Thus Bodhidharma’s style was to turn the attention of the disciple 
inward to the mind, and into its empty nature. The Master leads the 
disciple into realizing that one’s mind by its very nature is equal to 
that of a fully awakened Buddha. Yet, when one recognizes the nature of 
one’s own mind, nothing is found there to cling to as ‘this is mind’. 
Discovering one’s own Buddhahood in the empty-mind is the essence and 
the way of Mahayana Buddhism.
Bodhidharma said,
You should realize that the cultivation of the Way does not exist 
apart from your mind. If your mind is pure, everything is pure as 
buddha-fields. As sutras states, “If the minds of beings are impure, 
beings are impure. If the minds of beings are pure, beings are pure,” 
and “To reach a buddha-field, purify your mind. As your mind becomes 
pure, everything becomes pure as buddha-fields.” (from the Breakthrough 
Discourse)
Dissolving the Mind

Though purifying mind is the essence of practicing the Way, it is not
 done by clinging at the mind as a glorified and absolute entity. It is 
not that one simply goes inward by rejecting the external world. It is 
not that the mind is pure and the world is impure. When mind is clear, 
the world is a pure-field. When mind is deluded, the world is Samsara. 
Bodhidharma said,
Seeing with insight, form is not simply form, because form depends on
 mind. And, mind is not simply mind, because mind depends on form. Mind 
and form create and negate each other.  …  Mind and the world are 
opposites, appearances arise where they meet. When your mind does not 
stir inside, the world does not arise outside. When the world and the 
mind are both transparent, this is the true insight.” (from the Wakeup 
Discourse)
Just like the masters of Madhyamaka, Bodhidharma too pointed out that
 mind and form are interdependently arising. Mind and form create each 
other. Yet, when you cling to form, you negate mind. And, when you cling
 to mind, you negate form. Only when such dualistic notions are 
dissolved, and only when both mind and the world are transparent (not 
turning to obstructing concepts) the true insight arises.
In this regard, Bodhidharma said,
Using the mind to look for reality is delusion. 
Not using the mind to look for reality is awareness.
(from the Wakeup Discourse)
So, to effectively enter the Way, one has to go beyond the dualities 
(conceptual constructs) of mind and form. As far as one looks for 
reality as an object of mind, one is still trapped in the net of 
delusion (of seeing mind and form as independent realities), never 
breaking free from it. In that way, one holds reality as something other
 than oneself, and even worse, one holds oneself as a spectator to a 
separate reality!
When the mind does not stir anymore and settles into its pristine 
clarity, the world does not stir outside. The reality is revealed beyond
 the divisions of Self and others, and mind and form.  Thus, as you 
learn not to use the mind to look for reality and simply rests in the 
natural state of mind as it is, there is the dawn of pristine awareness 
–  knowing reality as it is, non-dually and non-conceptually.
When the mind does not dissolve in this way to its original clarity, 
whatever one sees is merely the stirring of conceptuality. Even if we 
try to construct a Buddha’s mind, it only stirs and does not see 
reality. Because, the Buddha’s mind is simply the uncompounded clarity 
of Bodhi (awakening), free from stirring and constructions. So, 
Bodhidharma said,
That which ordinary knowledge understands is also said to be within 
the boundaries of the norms. When you do not produce the mind of a 
common man, or the mind of a sravaka or a bodhisattva, and when you do 
not even produce a Buddha-mind or any mind at all, then for the first 
time you can be said to have gone outside the boundaries of the norms. 
If no mind at all arises, and if you do not produce understanding nor 
give rise to delusion, then, for the first time, you can be said to have
 gone outside of everything. (From the Record #1, of the Collection of 
Bodhidharma’s Works retrieved from Dunhuang Caves)
Often, this approach of simply not using mind and the instruction to 
rest naturally, are confused with  simply sitting in tranquility or 
Shamatha. Particularly, those who did not obtain the direct and clear 
instructions confuse so. Then, though they keep meditating, they do not 
enter the Way. However, if one understands Bodhidharma’s approach 
properly, it is not about holding mind in a passive state. His Way is a 
union of Shamatha (pacification of mind) and Vipashyana (cultivating 
insight). For example, Bodhidharma gave the following instructions 
regarding how to work with the mind that arises,
When mind arises, rely on teachings to watch the source where it 
arises from. If mind discriminates, rely on teachings to watch the 
source of discrimination. If attachment, anger or deluded thoughts 
arise, rely on teachings to watch the source they arise from. [When 
nothing arises,] not seeking for their arisings is cultivating the Way. 
When there is arising of thought, then investigate, and by relying on 
teachings, clear it up!(From the Record #1, of the Collection of 
Bodhidharma’s Works retried from Dunhuang Caves)
As it is evident from the above, Bodhidharma’s approach of dissolving
 mind is through insight, and not that of holding mind in a passive 
state. Various states of meditation attained through simply pacifying 
mind into various states of absorption (dhyana) are merely temporary and
 do not lead to real insight and liberation. Whereas, when  the 
dualistic mind is dissolved through insight, and then by simply resting 
in that insight, there is the view of reality, and thus liberation.
Thus, Bodhidharma clarified,
Not creating delusion is enlightenment.
Not engaging in ignorance is wisdom
No affliction is Nirvana.
(from the Wakeup Discourse)
Breaking the Silence
Bodhidharma kept silence for many years and stayed in a Samadhi of clear insight. He said,
Freeing oneself from words is liberation. (from the Wakeup Discourse)
The words, even when not spoken out, are proliferations of a 
conceptual and dualistic mind. To dissolve mind, it is important to free
 oneself from such proliferations and be able to rest naturally. Yet, he
 cautioned that a dumb kind of silence should not be confused as the 
Way. So, in the same discourse, he mocked those who glorify the silence 
of stupidity,
Those who understand both speech and silence are in Samadhi. If you 
speak when you know, your speech is free. If you are silent when you 
don’t know, your silence is bondage. If your speech is not attached to 
appearances, it is free. If your silence is attached to appearances, it 
is bondage. Language by itself is not bondage. Because, language by 
itself is not attachment. And, attachment has nothing to do with 
language. (from the Wakeup Discourse)
Clearly, it does not matter whether you speak or keep silence as far 
as either of it is from a point of wisdom and understanding. And, even 
the silence can be bondage if there is attachment and the lack of 
insight. In fact, the depth of inner silence of realization can pervade 
every spoken word. Then, words transcend silence and stirring.
The Two Ways to Enter the Way
Bodhidharma (Daruma) – a 15th Century painting. (Photo courtesy – Kyoto National Museum)
 
Bodhidharma’s approach to the Way can be classified into two methods.
 In one of his famed teachings in China, he spoke of these two kinds of 
entry to the Way. They are,
- Entering the Way through Insight – The instantaneous Entrance to the Way
 
- Entering the Way through Practice – The Gradual Entrance to the Way
 
Entering the Way through Insight
Entering the Way through insight happens when a disciple of high 
caliber listens to the instructions of the master, and then leaving 
behind all deluded pursuits, directly gains insight into the empty 
nature of mind. Then without making distinction between self and others,
 one maintains a stable and clear mind like a wall. This is the 
instantaneous entrance to the Way that Bodhidharma is most well known 
for. Relaxing in the stable and clear nature of the empty mind is the 
meditation that is unmoving like a wall. Unmoving does not mean that the
 mind is lost in vacuity with no thought and perception at all. It also 
does not mean that one is just sitting all the time. It is not that kind
 of unmoving. Even while various perceptions and experiences arise, one 
remains unmoving from the insight of the empty nature of mind and 
evenness of knowing that all beings possess Buddha-nature. As 
Bodhidharma said,
To transcend motion and stillness is the highest meditation. (from the Wakeup Sermon)
In this way, Bodhidharma’s approach is not that of just remaining 
still in body and mind, but that of meditation transcending motion and 
stillness. It is about maintaining unmoving realization of the reality 
throughout all actions of life, or simply, ‘unmoving meditation in 
action’.
Zen Master Dogen
 
The sitting meditation of Bodhidharma is also known as ‘Wall-gazing Meditation’ (
Pi-kuan
 in Chinese). Though in certain traditions of Chan/Zen, it is practiced 
by facing a wall, its meaning is not limited to simply gazing at the 
wall. In this, one trains to abandon all conceptuality and relax in the 
utter clarity of mind. As a poetic expression, it is like directly 
‘gazing’ into the empty wall of the  mind’s nature. However, in practice
 there is nothing to gaze as the nature of mind transcends 
object-subject dualities. So one simply relaxes in the natural clarity 
of mind.
Often, Bodhidharma’s approach of entering the Way through insight is 
confused with purely sitting meditation, devoid of everything else. In 
fact, his tradition got the name Zen School or Chan School (which 
literally means Meditation School) because ordinary people confused this
 to be just always sitting in meditation. As Dogen, a later master of 
Zen and the founder of Soto School of Zen in Japan pointed out in his 
Bendowa,
At first, while Master Bodhidharma sat facing the wall for nine years
 …, both monks and non-monastics … called him the sage who just 
practiced zazen (sitting meditation) as the essence. After that, his 
successors for generations practiced zazen. Seeing this, foolish worldly
 people, who did not understand what goes on in the sitting, in 
confusion [of seeing only the outer form] called this the ‘Zazen School’
 (the school of sitting meditation). … Do not take zazen to be same as 
the samadhi [of the three trainings of discipline, samadhi and wisdom], 
or dhyāna (meditation) of the six perfections. [The true zazen practice 
is what] Tathagata in the assembly at Vulture Peak (Grhakuta Mountain of
 Rajgir) transmitted to Venerable Mahakashyapa, the unsurpassed great 
transmission of the wondrous mind of Nirvana, the vision of dharma-eye. …
 It is a complete Way of Buddhadharma 
Entering the Way through Practice
Though the instantaneous approach of entering the Way through insight
 appears simple, it is difficult to gain instantaneous insight for most 
people even when a Master guides them to the view. So, Bodhidharma also 
taught a gradual way of entrance to the Way that is easy for all. This 
is ‘entering the Way through practice’. This has four practices,
- Accepting Suffering
 
- Adapting to Conditions
 
- Seeking nothing
 
- To unite with the Way
 
The first step in the gradual way is to learn not to react foolishly 
to sufferings arising from karmic ripening of past deeds. By reacting 
negatively, we only add more fuel to the karmic ripenings. In the face 
of painful situations that life presents, a skillful practitioner spends
 his or her energy in creating positive conditions and doing positive 
deeds rather than lamenting or reacting to painful situations 
negatively. This brings a first level sanity to life.

The
 second step is a little more advanced. Adapting to conditions is about 
realizing that all painful and pleasurable incidents of life are 
conditional and would also go away as conditions change. A skillful 
practitioner learns to maintain evenness of mind during both happiness 
and suffering, without giving into excessive elations and depression. 
This leads to profound clarity and  peace of mind.
The third step is even more advanced. Seeking nothing means that one 
has already realized a mind of contentment and  sees the meaninglessness
 of all selfish pursuits. In this stage, one even abandons seeking 
enlightenment. It does not mean that one remains inactive or shies away 
from action. Rather, one enjoys engaging in heroic pursuits for the 
benefit of others. (same as relative bodhicitta.)
As the final stage of the gradual way, the practitioner unites with 
the Way by seeing the emptiness of Self and all phenomena and by 
recognizing the empty expanse of the ground of all phenomena.
Honoring the Words of the Buddha
Though Bodhidharma emphasized the need to go to the essential meaning
 than merely reading scriptures, he also valued scriptural knowledge. In
 fact, Bodhidharma held Sutras in high esteem. Particularly he held that
 Mahayana Lankavatara Sutra contains the essential teachings of the 
instantaneous realization tradition of Mahayana. When Bodhidharma made 
Huike his Dharma successor, along with his robe and bowl he passed on a 
copy of the scripture of Lankavatara Sutra.
The Teachings Go further East
Bodhidharma’s teachings spread mainly in China and further east in 
Korea and Japan. His teachings later evolved into the instantaneous 
tradition of the Southern Chan school of China and the gradual tradition
 of the Northern Chan school of China. These teachings reached Vietnam 
through an Indian master named Vinītaruci who was a disciple of the 
Chinese master Sengcan, who in turn was a disciple of Huike, the heart 
disciple of Bodhidharma.  In Vietnam this school came to be known as the
 Thien school. The Chinese Chan school propagated to Japan when Myoan 
Eisai learnt it in China and established the Rinzai Zen School, 
following the Chinese tradition of the Linji Chan school.  Further, 
Dogen learnt from the Chinese tradition of the Caodong Chan school and 
established the Soto Zen school in Japan. All of these schools practice 
the meditation of just sitting and resting in the unborn nature of all 
appearances without seeking or rejecting appearances. The difference 
among these schools is in the additional supports they use such as Sutra
 recitation, contemplation on koans (verses, often with seemingly 
paradoxical meaning, supposed to take the disciple beyond 
conceptuality), walking meditation, etc.
Placing in a Broader Context
During the 8th century CE, Bodhidharma’s teachings (Chan) reached 
Tibet from China. And that provides a unique opportunity to review 
Bodhidharma’s teachings in the context of many other Mahayana Buddhist 
teachings that arrived in Tibet. Tibetan Buddhism had both the pandita 
methods (those who made thorough scholarly study to enter the Way of 
awakening) and the kusulu methods (those who just practiced the essence 
of non-conceptual realization, without much scholarly study). These 
pandita and kusulu methods blended into an integral whole in Tibet with 
the same lineages and masters handling both kinds of methods together. 
Thus, the Tibetan scholars were able to come up with some of the best 
works of systematizing, contrasting and co-developing various methods of
 awakening, without denigrating one style for another. Since Chan 
tradition did not survive in Tibet for long, Bodhidharma’s teachings do 
not occupy a place in the analytical works of later Tibetan scholars. 
However, during the short period of the Chan presence in Tibet, some 
important scholarly works were composed that covered Bodhidharma’s 
tradition.
Nub Sangye Yeshe’s Classification of the Four Systems
Nubchen Sangye Yeshe
 
Amongst those were Nubchen Sangye Yeshe’s composition of a very 
important work, with the name Samten Migdron (Lamp to the Eye of 
Meditation). Nubchen was a direct disciple of Guru Padmasambhava who 
brought Vajrayana Buddhism from India to Tibet. Nubchen’s work analyzed 
all the traditions of Mahayana Buddhist meditation into four systems 
with equal respect. This work also helps to distinguish between Chan / 
Zen and Atiyoga, and to avoid mixing up of the two methods.
Samten Migdron was lost for a long time. A manuscript of this text 
was recovered in early 20th Century from the Dunhuang caves in China. 
This became a very helpful source to see how Bodhidharma’s teaching 
style fits within the broader context of Mahayana Buddhism.
Nubchen classified Mahayana Meditation of the union of Shamatha 
(calm-abiding meditation) and Vipashyana (insight meditation) broadly 
into four systems. These are
Two methods of Sutrayana
- Gradual
 
- Instantaneous 
 
 and the two of Vajrayana
- Mahayoga (generation and completion stage practices of Mantrayana) 
 
- Atiyoga (the Great Perfection or Dzogchen practice). 
 
All of these four have their own respective ways of arriving at the 
union of shamatha and vipashyana on the unborn and empty nature of the 
basic space of all phenomena, and attaining liberation in that basic 
space.
According to Nubchen’s classification, the Gradual Sutrayana refers 
to the path of gradually abandoning various conceptual clingings and 
gradually realizing the unborn and empty nature of the space of all 
phenomena. Here, one cultivates non-conceptuality with respect to 
various phenomenal appearances, and that gradually leads to the basic 
space.
The second system, the Instantaneous Sutrayana, is what Nubchen 
identifies  primarily as the teachings of the Great Abbot 
Bodhidharmottara (or Bodhidharma), particularly ‘Entering the Way 
through Insight’ (Nubchen also deals with many other masters of Chan / 
Zen as belonging to this category). According to Nubchen, this method 
teaches the unborn nature of the space of all phenomena from the very 
beginning. The practice here is that of wall-gazing as the union of 
shamatha and vipashyana by training to rest in the unborn ultimate 
nature. According to Nubchen, this unborn nature is the 
parinishpanna svabhāva
 (Perfect Nature) of the unborn space as in Yogacara. Here one 
cultivates non-conceptuality with respect to the emptiness of all 
phenomena. In other words, one cultivates non-conceptuality with respect
 to non-appearances, without clinging to a conceptual notion of emptiness.
The third, Mahayoga, refers to the generation and completion stage 
practices of the Vajrayana. Here, one cultivates the non-dual 
non-conceptuality of the inseparability of the unborn space and 
wisdom-appearances.
The fourth, Atiyoga, refers to Great Perfection or Dzogchen. Here, a 
disciple is directly introduced to the play of his or her pristine 
awareness that is inseparable from the unborn space of all phenomena. In
 Atiyoga, one directly rests in the spontaneously present 
non-conceptuality where there is no reference for meditation, such as 
the object or subject. In this spontaneously present non conceptuality, 
emptiness and appearances are naturally unified.
Prasangika Madhyamaka and Bodhidharma
In the context of the above analysis, it is also interesting to 
compare Prasangika Madhyamaka with Bodhidharma’s method. Though these 
two methods of entering the Way differ drastically, the qualities of 
their meditation are essentially the same.
Prasangika uses consequential reasoning (the logic of 
reduction-ad-absurdum) to see the absurdity of every possible conceptual
 elaboration. Here, conceptual elaborations include the views such as 
existence, non-existence, both and neither. As one studies scriptures 
and thoroughly analyzes, one gains certainty in the absurdity of all 
such conceptual positions. Having gained certainty through such analysis
 and contemplation, one’s mind comes to rest in the uncontrived nature 
of mind, giving rise to self-arisen wisdom that is in the nature of 
mind. (Nubchen Sangey Yeshe did not analyze Prasangika as a separate 
system in Samten Migdron. However, since the Prasangika approach is to 
cut all extremes of existence, non-existence and so on simultaneously, 
its meditation is the same as what Nubchen explains for the 
Instantaneous Sutrayana, namely, that of non-conceptuality of 
non-appearance.)
Unlike Prasangika, Chan / Zen does not use elaborate logic and 
reasoning to analyze every possible position. Instead, a disciple in 
this case relies on the individualized instructions of a realized Master
 to move from the position where he or she is stuck  to the point of 
gaining glimpse into the view of the unborn nature. The effectiveness of
 this approach depends on the ability of both the master and the 
disciple. Though a detailed Madhyamaka style analysis is not performed, 
some systems of Chan / Zen use riddles (koan). Riddles are chosen by the
 Master depending upon where the disciple is stuck currently. The real 
Chan / Zen according to ‘Entering the Way through Insight’ 
(Instantaneous Entrance) starts only when gradually the disciple arrives
 at the gate of having a glimpse of the unborn nature.

It is not only about recognizing the reflections as reflections, but also recognizing that there is no mirror (no mind)! Knowing that everything is a projection of mind, is just part of the hundreds and thousands of explanations that lead the disciple. Further, when you directly see and understand (recognize) the nature of yourself, the nature of your own mind, only then you see and truly understand the meaning of even the statement, “everything is projection of mind”.
