There is a famous proverb about a teacup. Although there are multiple versions, here is my favorite one:
Once upon a time, there was a wise Zen master. People traveled from far away to seek his help. In return, he would teach them and show them the way to enlightenment.
On this particular day, a scholar came to visit the master for advice. “I have come to ask you to teach me about Zen,” the scholar said.
