Guru: What is the source of light for you? Disciple: To me, during the day, it is the Sun and at night, it is lamp and the like. Guru: Tell me what reveals the Sun as well as the lamp. Disciple: The eyes. Only when the eyes are there, can we see. Guru: Suppose the eyes are closed. Then what reveals everything? Disciple: When the eyes are closed, it is the intelligence which is the source of revelation. Guru: Well, what reveals the intelligence? Disciple: It is my own self. The "I". Guru: My child, do you now understand? You alone are the supreme brilliance, the ultimate light. The first and the last source of illumination. Is it not? Disciple: Yes, O Master. I am that.
