Śrī Caitanya Mahāprabhu decided to accept the order and become an ideal sannyāsī so that the general populace would show Him respect. One is duty-bound to show respect to a sannyāsī, for a sannyāsī is considered to be the master of all varṇas and āśramas.
While He was contemplating accepting the sannyāsa order, it so happened that Keśava Bhāratī, a sannyāsī of the Māyāvādī school and resident of Katwa (in Bengal), visited Navadvīpa and was invited to dine with the Lord. When Keśava Bhāratī came to His house, the Lord asked him to award Him the sannyāsa order of life. This was a matter of formality. The sannyāsa order is to be accepted from another sannyāsī.
