Dhruva Maharaja thought to himself: To endeavor to be situated in the shade of the lotus feet of the Lord is not an ordinary task because even the great brahmacaris headed by Sanandana, who practiced astanga-yoga in trance, attained the shelter of the Lord’s lotus feet only after many, many births. Within six months I achieved the same result, yet due to my thinking differently from the Lord, I fell down from my position.
