PURPORT

Srila Jiva Gosvami has translated this verse as follows. "The Supreme Personality of Godhead is the cause of all causes. It is by His will that gross and subtle ingredients interact. He appears in various incarnations just to please the hearts of His pure devotees." For example, the Supreme Lord appeared in the transcendental incarnation of Lord Varaha (the boar) just to please His devotees by lifting the planet earth from the Garbhodaka Ocean.
