In doing zazen it is desirable to have a quiet room. You should be temperate in eating and drinking, forsaking all delusive relationships.

The one and only thing required is to free oneself from the bondage of mind and body alike, putting the Buddha's own seal upon yourself.

A fish swims in the ocean, and no matter how far it swims there is no end to the water. A bird flies in the sky, and no matter how far it flies there is no end to the air. However the fish and the bird have never left their elements. Thus each of them totally covers its full range, and each of them totally experiences its realm... Know that water is life and air is life. The bird is life and the fish is life. Life must be the bird and life must be the fish... practice, enlightenment and people are like this.
