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

The essence of the Way is detachment.

The Dharma is the truth that all natures are pure.

At every moment where language can't go, that's your mind.

Unless you see your nature, you shouldn't go around criticizing the goodness of others. There's no advantage in deceiving yourself. Good and bad are distinct. Cause and effect are clear. But fools don't believe and fall straight into a hell of endless darkness without even knowing it. What keeps them from believing is the heaviness of their karma. They're like blind people who don't believe there's such a thing as light. Even if you explain it to them, they still don't believe, because they're blind. How can they possibly distinguish light?

To go from mortal to Buddha, you have to put an end to karma, nurture your awareness, and accept what life brings.

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.
