Translation
"O Lord Krishna, please protect Me and maintain Me" (Chaitanya-charitamrita, Madhya 7.96).
Meaning
Sri Chaitanya Mahaprabhu Himself chanted these names while travelling through South India: "Krishna! Keshava! … pahi mam" and "Rama! Raghava! … raksha mam." Keshava means "slayer of the demon Keshi", Raghava is Rama, descendant of Raghu. Taking shelter of the Lord's name for protection is the heart of Gaudiya Vaishnava practice.
