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. So Zen is keeping the mind which is before thinking. Sciences and academic studies are after thinking. We must return to before thinking. Then we will attain our true self.
