Lord Nityananda is the eternal associate of Chaitanya Mahaprabhu, the Supreme Personality of Godhead. Rarely is the name Nimai (Chaitanya Mahaprabhu) taken without that of Nitai (Lord Nityananda). Mahaprabhu cannot be approached or understood without the mercy of Nityananda Prabhu, who is the cardinal guru of all the universes and serves as an intermediary between Mahaprabhu and His Devotees.
