The Supreme Personality of Godhead said: O beloved demigods, you have offered your prayers to Me with great knowledge, and I am certainly most pleased with you. A person is liberated by such knowledge, and thus he remembers My exalted position, which is above the conditions of material life. Such a devotee is fully purified by offering prayers in full knowledge. This is the source of devotional service to Me.
