Because in Vedic literature there are recommendations for worshiping different gods for different purposes (e.g., a diseased man is recommended to worship the sun), those who are not devotees of the Lord think that for certain purposes demigods are better than the Supreme Lord. But a pure devotee knows that the Supreme Lord Kåñëa is the master of all. In the Caitanya-caritämåta it is said that only the Supreme Personality of Godhead, Kåñëa, is master and all others are servants. Therefore a pure devotee never goes to demigods for satisfaction of his material needs. He depends on the Supreme Lord. And the pure devotee is satisfied with whatever He gives.
