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.... Using the mind to reality is delusion. Not using the mind to look for reality is awareness. Freeing oneself from words is liberation.
One clings to life although there is nothing to be called life; another clings to death although there is nothing to be called death. In reality, there is nothing to be born; consequently, there is nothing to perish.
If you use your mind to study reality, you won't understand either your mind or reality. If you study reality without using your mind, you'll understand both. . . . The mind and the world are opposites, and vision arises where they meet. When your mind doesn't stir inside, the world doesn't arise outside. When the world and the mind are both transparent, this is true vision. And such understanding is true understanding.
When mortals are alive, they worry about death. When they're full, they worry about hunger. Theirs is the Great Uncertainty. But sages don't consider the past. And they don't worry about the future. Nor do they cling to the present. And from moment to moment they follow the Way.
To have a body is to suffer. Does anyone with a body know peace? Those who understand this detach themselves from all that exists and stop imagining or seeking anything. The sutras say, "To seek is to suffer. To seek nothing is bliss." When you seek nothing, you're on the Path.
