This is the divinity of the Personality of Godhead: He is not affected by the qualities of material nature, even though he is in contact with them. Similarly, the devotees who have taken shelter of the Lord do not become influenced by the material qualities.
Who can be worthy of the name of the Supreme Lord but the Personality of Godhead Sri Krishna? Brahmaji collected the water emanating from the nails of His feet in order to award it to Lord Siva as a worshipful welcome. This very water [the Ganges] is purifying the whole universe, including Lord Siva.
Life's desires should never be directed towards sense gratification. One should desire only a healthy life, or self-preservation, since a human being is meant for inquiry about the Absolute Truth. Nothing else should be the goal of one's works.
Sri Krishna, the Personality of Godhead, who is the Paramatma [Supersoul] in everyone's heart and the benefactor of the truthful devotee, cleanses desire for material enjoyment from the heart of the devotee who has developed the urge to hear His messages, which are in themselves virtuous when properly heard and chanted.
