Zazen practice and everyday activity are one thing. We call zazen everyday life, and everyday life zazen.

The mind we have when we practice zazen is the great mind: we don't try to see anything; we stop conceptual thinking; we stop emotional activity; we just sit. Whatever happens to us, we are not bothered. We just sit. It is like something happening in the great sky. Whatever kind of bird flies through it, the sky doesn't care. That is the mind transmitted from Buddha to us.

The secret of zen is just two words: not... always... so.

When something dies is the greatest teaching.

Life and death are the same thing. When we realize this fact, we have no fear of death anymore, nor actual difficulty in our life.

We die, and we do not die.

So the secret is just to say 'Yes!' and jump off from here. Then there is no problem. It means to be yourself, always yourself, without sticking to an old self.
