The koans do not represent the private opinion of a single man, but rather the highest principle . . . that accords with the spiritual source, tallies with the mysterious meaning, destroys birth-and-death, and transcends the passions. It cannot be understood by logic; it cannot be transmitted in words; it cannot be explained in writing; it cannot be measured by reason. It is like . . . a great fire that consumes all who come near it.
