The Zen Teaching of Bodhidharma - Translated and with an Introduction by Red Pine (PDF)
"Whoever realizes that the six senses aren't real, that the five aggregates are fictions, that no such things can be located anywhere in the body, understands the language of buddhas. The sutras say, "The cave of five aggregates is the hall of zen. The opening of the inner eye is the door of the Great Vehicle." What could be clearer?"
"Not thinking about anything is zen. Once you know this, walking, standing, sitting, or lying down, everything you do is zen. To know that the mind is empty is to see the buddha. The buddhas of the ten directions have no mind. To see no mind is to see the buddha. To give up yourself without regret is the greatest charity. To transcend motion and stillness is the highest meditation. Mortals keep moving, and arhats stay still. But the highest meditation surpasses both that of mortals and that of arhats. People who reach such understanding free themselves from all appearances without effort and cure all illnesses without treatment. Such is the power of great zen."
"Using the mind to look for reality is delusion. Not using the mind to look for reality is awareness. Freeing oneself from words is liberation. Remaining unblemished by the dust of sensation is guarding the Dharma. Transcending life and death is leaving home. Not suffering another existence is reaching the Way. Not creating delusions is enlightenment. Not engaging in ignorance is wisdom. No affliction is nirvana. And no appearance of the mind is the other shore."
