Through [Zen] sitting practice you will develop some kind of stability in your life. There's something very deep and immovable in yourself that was always there, just like right now there are some buds on the trees and plants, little ones. And if you were to look, even in the deep snow you'd discover some small sprouts already growing. There's a Japanese word, anshin, that is very important for us to understand. Basically it means "calm, serene, undisturbed." But its meaning reaches much further than those words. Anshin implies that the question of the self has been settled. The question of life and death has been resolved, and your spiritual question has been fulfilled. That's true liberation.
