Prajna

From "Entering the Tao of Sudden Enlightenment" by Ch'an Master Ta-Chu Hui-Hai

A monk once asked: "Is Prajna great?"

The Master answered: "Yes, it is."

The monk asked: "How great?"

The Master answered: "Boundless."

The monk asked: "Is Prajna small?"

The Master answered: "Yes, it is."

The monk asked: "How small?"

The Master answered: "So small you can't see it."

The monk asked: "Then where is it?"

The Master answered: "Where is it not?"
