Zen - the way

There are many avenues for entering the Way, but essentially they all are of two kinds: entering through the Principle [cosmic order] and entering through practice.
  "Entering through the Principle" is awakening to the essential by means of the teachings. It requires a profound trust that all living beings, both enlightened and ordinary, share the same true nature, which is obscured and unseen due only to mistaken perception. If you turn from the false to the true, dwelling steadily in wall contemplation, there is no self or other, and ordinary people and sages are one and the same. You abide unmoving and unwavering, never again confused by written teachings. Complete, ineffable accord with the Principle is without discrimination still, effortless. This is called entering through the Principle.
  "Entering through practice" refers to four all-encompassing practices: the practice of requiting animosity, the practice of accepting one's circumstances, the practice of craving nothing and the practice of accord with the Dharma.
