ONCE, a king asked a yogi to impart Knowledge to him in one word. The yogi said, "All right; you will get knowledge in one word." After a while a magician came to the king. The king saw the magician moving two of his lingers rapidly and heard him exclaim, "Behold, O king, Behold." The king looked at him amazed when, after a few minutes, he saw the two lingers becoming one. The magician moved that one finger rapidly and said, "Behold, O king! Behold."
The implication of the story is that Brahman and the Primal Energy at first appear to be two. But after attaining knowledge of Brahman one does not see the two. Then there is no differentiation; it is One, without a second— Advaita—non-duality.
