People of this world are deluded. They're always longing for something - always, in a word, seeking.
Life and death are important. Don't suffer them in vain.
But people of the deepest understanding look within, distracted by nothing. Since a clear mind is the Buddha, they attain the understanding of a Buddha without using the mind.
Delusion means mortality. And awareness means Buddhahood.
Reality has no inside, outside, or middle part.
If you see your nature, you don't need to read sutras or invoke buddhas. Erudition and knowledge are not only useless but also cloud your awareness. Doctrines are only for pointing to the mind. Once you see your mind, why pay attention to doctrines?
