Finally, the tea is ready, and the teacher begins to pour a cup for his visitor. The small cup fills to the brim and the teacher, still looking at his guest, keeps pouring. The cup overflows and tea begins to spill across the table, and down, onto the student’s lap. After an uncomfortable moment, the student finally jumps up and yells, “Stop, master! Stop! The cup is full. You can’t put any more in.” The master, still smiling and still looking at the student, slowly stopped pouring the tea, and says, "Yes the cup is just like you. Already full. I will not be able to teach you anything until you come to me with a cup that is empty."
