Bodhidharma, the first Zen patriarch of China:

'To find a Buddha all you have to do is see your nature (見性). Your nature is the Buddha. And the Buddha is the person who's free: free of plans, free of cares. If you don't see your nature and run around all day looking somewhere else, you'll never find a buddha. The truth is there's nothing to find.'

(The Zen Teaching of Bodhidharma, p 13; T48, no. 2009, p. 373c17-20)

'To attain enlightenment (成佛) you have to see your nature (見性). Unless you see your nature, all this talk about cause and effect is nonsense (外道法). Buddhas don't practice nonsense. A Buddha free of karma free of cause and effect. To say he attains anything at all is to slander a Buddha. What could he possibly attain? Even focusing on a mind, a power, an understanding, or a view is impossible for a Buddha. A Buddha isn't one sided. The nature of his mind is basically empty, neither pure nor impure. He's free of practice and realization (無修無證).'

(p 17; p. 374a15-20)

'People who don't see their nature (見性) and imagine they can practice thoughtlessness (無作想) all the time are liars and fools. They fall into endless space. They're like drunks. They can't tell good from evil. If you intend to cultivate such a practice (無作法), you have to see your nature (見性) before you can put an end to rational thought (息緣慮). To attain enlightenment without seeing your nature is impossible.'

(p 19; p. 374a24-27)

'Buddha is Sanskrit for what you call aware (覺性), miraculously aware (靈覺). Responding, arching your brows blinking your eyes, moving your hands and feet, its all your miraculously aware nature. And this nature is the mind. And the mind is the Buddha. And the Buddha is the path. And the path is Zen. But the word Zen is one that remains a puzzle to both mortals and sages. Seeing your nature (見本性) is Zen. Unless you see your nature, it's not Zen.'

(p 29; p. 375a5-9)

'Once mortals see their nature (見本性), all attachments end. Awareness (神識) isn't hidden. But you can only find it right now. It's only now. If you really want to find the Way, don't hold on to anything. Once you put an end to karma and nurture your awareness (神), any attachments that remain will come to an end. Understanding comes naturally. You don't have to make any effort. But fanatics (外道) don't understand what the Buddha meant. And the harder they try, the farther they get from the Sage's meaning. All day long they invoke Buddhas and read sutras. But they remain blind to their own divine nature (神性), and they don't escape the Wheel.

A buddha is an idle person. He doesn't run around after fortune and fame. What good are such things in the end? People who don't see their nature (見性) and think reading sutras, invoking Buddhas', studying long and hard, practicing morning and night, never lying down (長坐不臥), or acquiring knowledge is the Dharma, blaspheme the Dharma. Buddhas of the past and future only talk about seeing your nature (見性). All practices are impermanent. Unless they see their nature (見性) people who claim to have attained unexcelled, complete enlightenment are liars.'

(p 35-37; p. 375b22-c3)

'Basically, seeing, hearing, and knowing (見聞覺知) are completely empty (本自圓寂). Your anger, Joy, or pain is like that of puppet. You can search but you won't find a thing. According to the sutras, evil deeds result in hardships and good deeds result in blessings. Angry people go to hell and happy people go to heaven. But once you know that the nature of anger and joy is empty and you let them go, you free yourself from karma.'

(p 45; p. 376b2-6)

'Someone who seeks the Way doesn't look beyond himself. He knows that the mind is the Way. But when he finds the mind, he finds nothing. And when he finds the Way, he finds nothing. If you think you can use the mind to find the Way, you're deluded. When you're deluded, buddhahood exists. When you're aware, it doesn't exist. This is because awareness is buddhahood.'

(Wake-up Sermon, in The Zen Teaching of Bodhidharma, p 59; T48, no. 2009, p. 371c10-13)

'To see form but not be corrupted by form or to hear sound but not be corrupted by sound is liberation. Eyes that aren't attached to form are the Gates of Zen. Ears that aren't attached to sound are also the Gates of Zen. In short, those who perceive the existence and nature of phenomena and remain unattached are liberated. Those who perceive the external appearance of phenomena are at their mercy. Not to be subject to affliction is what's meant by liberation. There's no other liberation. When you know how to look at form, form doesn't give rise to mind and mind doesn't give rise to form. Form and mind are both pure.'

(Wake-up Sermon, in The Zen Teaching of Bodhidharma, p 61; T48, no. 2009, p. 371c17-23)
