"Narottama dasa Thakura sings, chadiya vaisnava-seva nistara payeche keba: "Who has been elevated without rendering service to a pure Vaisnava?" It is the statement of Prahlada Maharaja that unless one is able to accept the dust from the lotus feet of a pure Vaisnava there is no possibility of achieving the platform of devotional service. That is the secret."
(Caitanya-Caritamrita, Adi-lila 8.17 Purport)
