The Guru is the Self. At some time a man grows dissatisfied with his life and, not content with what he has, seeks the satisfaction of his desires through prayer to God. His mind is gradually purified until he longs to know God, more to obtain His Grace than to satisfy worldly desires. Then God’s grace begins to manifest. God takes the form of a Guru and appears to the devotee, teaches him the Truth and, moreover, purifies his mind by association with him. The devotee’s mind thus gains strength and is then able to turn inward. By meditation it is further purified until it remains calm without the least ripple. That calm Expanse is the Self.
