To enter by reason means to realize the essence through instruction and to believe that all living things share the same true nature, which isn't apparent because it's shrouded by sensation and delusion.

Buddhas move freely through birth and death, appearing and disappearing at will.

To have a body is to suffer.

Leaving behind the false, return to the true: make no discriminations between self and others. In contemplation, one's mind should be stable and unmoving, like a wall.

Not thinking about anything is Zen. Once you know this, walking, sitting, or lying down, everything you do is Zen.

Externally keep yourself away from all relationships, and internally have no pantings in your heart; when your mind is like unto a straight-standing wall, you may enter into the Path.

As long as you look for a Buddha somewhere else, you'll never see that your own mind is the Buddha
