A newcomer went to his sponsor. He asked him to explain the meaning of the spiritual experience. The sponsor quietly poured a cup of tea. The cup was full but he continued to pour.
The newcomer could not stand this any longer, so he questioned his sponsor impatiently, “Why do you keep pouring when the cup is full?”
“I want to point out to you,” the sponsor said, “that you are similarly attempting to understand the spiritual experience while your mind is full. First, empty your mind of preconceptions before you attempt to understand the spiritual experience.”
