Clear mind is like the full moon in the sky. Sometimes clouds come and cover it, but the moon is always behind them. Clouds go away, then the moon shines brightly. So don't worry about clear mind: it is always there. When thinking comes, behind it is clear mind. When thinking goes, there is only clear mind. Thinking comes and goes, comes and goes, You must not be attached to the coming or the going.
SeungsahnPerceiving your own voice means perceiving your true self or nature. When you and the sound become one, you dont hear the sound; you are the sound.
SeungsahnIf you are thinking, you can't understand Zen. Anything that can be written in a book, anything that can be said - all this is thinking . . . but if you read with a mind that has cut off all thinking, then Zen books, sutras and Bibles are all the truth. So is the barking of a dog or the crowing of a rooster. All things are teaching you at every moment, and these sounds are even better teaching than Zen books.
