"It is said, therefore, by Vaisnava authorities that even the most intelligent person cannot understand the plans and activities of a pure devotee. The exact words are vaisnavera kriya mudra vijne na bujhaya. A person who is thus always engaged in the service of the Lord or is always thinking and planning how to serve the Lord is to be considered completely liberated at present and in the future. His going back home, back to Godhead, is guaranteed. He is above all materialistic criticism, just as Krsna is above all criticism."
