Awareness teachings in itself is nothing wrong. But what is its nature? That must be clear… Buddhism is the ultimate Awareness teaching, it reveals its anatman, empty and dependently originating nature of this “vivid awareness” with greatest clarity.

Unlike substantialist teachings which turn awareness into some ultimate reality, source and substratum, the changeless ground residing behind everything, the ultimate agent and so on. That is generally what “Awareness teachings” are nowadays. Simply realising and focusing on the aspect of luminous clarity and neglecting its empty nature. Turning it into an atman brahman teaching. This is misleading.

Also, he wrote in 2012, "Has awareness stood out? There is no concentration needed. When six entries and exits are pure and primordial, the unconditioned stands shining, relaxed and uncontrived, luminous yet empty. The purpose of going through the 7 phases of perception shift is for this... Whatever arises is free and uncontrived, that is the supreme path. Whatever arises has never left their nirvanic state... ... your current mode of practice [after those experiential insights] should be as direct and uncontrived as possible. When you see nothing behind and magical appearances are too empty, awareness is naturally lucid and free. Views and all elaborations dissolved, mind-body forgotten... just unobstructed awareness. Awareness natural and uncontrived is supreme goal. Relax and do nothing, Open and boundless, Spontaneous and free, Whatever arises is fine and liberated, This is the supreme path. Top/bottom, inside/outside, Always without center and empty (2-fold emptiness), Then view is fully actualized and all experiences are great liberation." In 2014, he said, "All 7 phases of insight can be realized and experienced, they are not verbiage. But perfection in terms of actualization in everyday life requires refining our view, meeting situations and dedication of quality time in anatta and total exertion. The problem is many do not have the discipline and perseverance."

These are phases I have been through in my experience, they are not theories. Some others may go through slightly different orders but generally my experience is that most will go through the phases in somewhat similar fashion.

Idk but if you go through the AtR guide (whether abridged or full version) it is quite safe because the pointers are all there. Beyond that you should find a teacher.

There are actually some teachers that take on students online which i think is quite good like ven jinmyo osho — see next post

And if you are interested in something like dzogchen, i can recommend acarya malcolm smith.

Also you can search around you and see if you can find teachers in your city that teach from realisation of anatta at least. Not easy or perhaps there isnt any around. But it is also possible that there are
