"The spiritual master is certainly very merciful to his disciples, and consequently by satisfying him a devotee gets strength from the Supreme Personality of Godhead. Sri Caitanya Mahaprabhu therefore says, guru-krishna-prasade paya bhakti-lata-bija: one must first please the spiritual master, and then one automatically pleases Krishna and gets the strength with which to cross the ocean of nescience."
(Srimad-Bhagavatam 7.15.45, Purport)
