This one life has no form and is empty by nature. If you become attached by any form, you should reject it. If you see an ego, a soul, a birth, or a death, reject them all.
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.
Still others commit all sorts of evil deeds, claiming karma doesn't exist. They erroneously maintain that since everything is empty, committing evil isn't wrong. Such persons fall into a hell of endless darkness with no hope of release. Those who are wise hold no such conception.
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.
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.
To see nothing is to perceive the Way, and to understand nothing is to know the Dharma, because seeing is neither seeing nor not seeing, and because understanding is neither understanding nor not understanding.
