When Kishizawa Ian, Suzuki Roshi's second teacher, was a young monk, he was sitting in meditation on a rainy day and heard the sound of a distant waterfall. Then the wooden han was struck. He went to his teacher (maybe Oka Sotan) and asked, "What is the place where the sound of the rain, the waterfall, and the han meet?"His teacher replied, "True eternity still flows."And then he asked, "What is this true eternity that still flows?""It is like a bright mirror, permanently smooth," said his teacher."Is there anything beyond this?" asked the young monk."Yes," responded his teacher."What is beyond this?" inquired the young monk.And his teacher replied, "Break the mirror. Come, and I'll meet you."
