CC Madhya 8.55
eka-bhṛtya-saṅge rāya mililā āsiyā
After finishing His evening bath, Śrī Caitanya Mahāprabhu sat down and waited for Rāmānanda Rāya to come. Then Rāmānanda Rāya, accompanied by one servant, came to meet Him.
A Vaiṣṇava who is supposed to be advanced in spiritual understanding — be he a householder or a sannyāsī — must bathe three times a day: morning, noon and evening. When one is engaged in the service of the Deity, he must especially follow the principles of the Padma Purāṇa and take regular baths. He should also, after bathing, decorate his body with the twelve tilakas.
