The capacity of the mind is broad and huge,like the vast sky. Do not sit with a mind fixed on emptiness. If you do, you will fall into a neutral kind of emptiness.Emptiness includes the sun, moon, stars, and planets, the great earth, mountains and rivers, all trees and grasses, bad men and good men, bad things and good things, heaven and hell. They are all in the midst of emptiness.
