CC Ādi 7.59
pāda prakṣālana kari vasilā sei sthāne
As soon as Śrī Caitanya Mahāprabhu saw the sannyāsīs He immediately offered obeisances, and then He went to wash His feet. After washing His feet, He sat down by the place where He had done so.
By offering His obeisances to the Māyāvādī sannyāsīs, Śrī Caitanya Mahāprabhu very clearly exhibited His humbleness to everyone. Vaiṣṇavas must not be disrespectful to anyone, to say nothing of a sannyāsī. Śrī Caitanya Mahāprabhu teaches, amāninā māna-dena: one should always be respectful to others but should not demand respect for himself. A sannyāsī should always walk barefoot, and therefore when he enters a temple or a society of devotees he should first wash his feet and then sit down in a proper place. In India it is still the prevalent custom that one put his shoes in a specified place and then enter the temple barefoot after washing his feet. Śrī Caitanya Mahāprabhu is an ideal ācārya, and those who follow in His footsteps should practice the methods of devotional life that He teaches us.
