A buddha is someone who finds freedom in good fortune and bad. Such is his power that karma can't hold him. No matter what kind of karma, a buddha transforms it. Heaven and hell are nothing to him. But the awareness of a mortal is dim compared to that of a buddha, who penetrates everything, inside and out.
The Way is basically perfect. It doesn't require perfecting. The Way has no form or sound. It's subtle and hard to perceive. It's like when you drink water: you know how hot or cold it is, but you can't tell others.
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.
Don't hate life and death or love life and death. Keep your every thought free of delusion, and in life you'll witness the beginning of nirvana, and in death you'll experience the assurance of no rebirth.
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.
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.
