A martial arts student was having tea with his Sensei. The student said, “Sensei, I've learned all you have to teach me about defending myself. I want to learn one thing more now. Please teach me about the ways of God.”
The Sensei took the teakettle from the table and began pouring the student's cup full of tea. Soon the cup was full and began to spill over onto the saucer. But the Sensei continued to pour the tea until it spilled over the saucer and then onto the floor.
The student finally said, “Stop, stop, the tea is spilling over. The cup can't take any more.” The Sensei then looked at the student and said, “You are so full of yourself that there is no room in your life for God. It is not possible for you to learn the ways of God until you learn to empty yourself.”
