All the great stalwart personalities in the universe, including Lord Brahma and Lord Siva, are fully under the control of the Supreme Personality of Godhead, but the Supreme Personality of Godhead is fully under the control of His devotee. Why is this? Because the devotee is anyabhilasita-sunya; in other words, he has no material desires in his heart. His only desire is to think always of the Supreme Personality of Godhead and how to serve Him best. Because of this transcendental qualification, the Supreme Lord is extremely favorable to the devoteesindeed, not only the devotees, but also the devotees of the devotees. Srila Narottama dasa Thakura says, chadiya vaisnava-seva nistara payeche keba: without being a devotee of a devotee, one cannot be released from material entanglement. Therefore Caitanya Mahaprabhu identified Himself as gopi-bhartuh pada-kamalayor dasa-dasanudasah. Thus he instructed us to become not directly servants of Krsna but servants of the servant of Krsna. Devotees like Brahma, Narada, Vyasadeva and Sukadeva Gosvami are directly servants of Krsna, and one who becomes a servant of Narada, Vyasadeva and Sukadeva, like the six Gosvamis, is still more devoted. Srila Visvanatha Cakravarti Thakura therefore says, yasya prasadad bhagavat-prasadah: if one very sincerely serves the spiritual master, Krsna certainly becomes favorable to such a devotee. Following the instructions of a devotee is more valuable than following the instructions of the Supreme Personality of Godhead directly.
