CC Madhya 6.56
ataeva haṅ tomāra āmi nija-dāsa’
“You are naturally respectable. Besides, You are a sannyāsī; thus I wish to become Your personal servant.”
A sannyāsī is always to be worshiped and offered all kinds of respect by the gṛhasthas (householders). Although Sārvabhauma Bhaṭṭācārya was older than Śrī Caitanya Mahāprabhu, Sārvabhauma respected Him as a sannyāsī and as one who had attained the topmost platform of spiritual ecstasy. Thus the Bhaṭṭācārya certainly accepted Him as his master.
