This is a beautiful song with with part of a chant done by those in Srila Prabhupada‘s Hare Krishna movement.
I offer my respectful obeisances unto Sri Caitanya Mahaprabhu, Lord Nityananda, Sri Advaita, Gadadhara Pandit, Srivas Thakur, and all the devotees of Lord Caitanya.
PURPORT by Srila Prabhupada
Sri Caitanya Mahaprabhu is always accompanied by His plenary expansion Sri Nityananda Prabhu, His incarnation Sri Advaita Prabhu, His internal potency Sri Gadadhara Prabhu, and His marginal potency Srivasa Prabhu. He is in the midst of them as the Supreme Personality of Godhead.
One should know that Sri Caitanya Mahaprabhu is always accompanied by these other tattvas. Therefore our obeisances to Sri Caitanya Mahaprabhu are complete when we say, sri-krishna-chaitanya prabhu nityananda sri-adwaita gadadhara shrivasadi-gaura-bhakta-vrinda. As preachers of the Krsna consciousness movement, we first offer our obeisances to Sri Caitanya Mahaprabhu by chanting this Panca-tattva mantra; then we say, Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare.
There are ten offenses in the chanting of the Hare Krsna maha-mantra, but these are not considered in the chanting of the Païca-tattva mantra, namely, sri-krishna-chaitanya prabhu nityananda sri-adwaita gadadhara shrivasadi-gaura-bhakta-vrinda. Sri Caitanya Mahaprabhu is known as maha-vadabtavatara, the most magnanimous incarnation, for He does not consider the offenses of the fallen souls.
Thus to derive the full benefit of the chanting of the maha-mantra (Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare), we must first take shelter of Sri Caitanya Mahaprabhu, learn the Panca-tattva mantra, and then chant the Hare Krsna maha-mantra. That will be very effective.
