The story goes that a monk named Ching-ch'ing came to Zen Master Hsuan-sha seeking instruction. Ching-ch'ing said, "I've come seeking the truth. Please, master, tell me how I can enter the way of Zen." Hsuan-sha said, "Can you hear the sound of the creek down beyond the gate?" Ching-ch'ing listened, and replied, "Yes, master, I can hear it." "Enter Zen from there," Hsuan-sha told him.
