The Case
A monk asked zen master Joshu, "Does a newborn baby possess the six senses or not?" Joshu said, "It is like throwing a ball into the rapids." The monk later asked Tosu, "What is the meaning of throwing a ball into the rapids'?" Tosu said, "Thought after thought without ceasing."
Verse
The question: the six senses. Purposeless. Well acquainted with it, the masters. A ball is thrown into the rapids, do you know where it is carried?
