CC Madhya 10.154
tāhā dekhi’ prabhu duḥkha pāilā antara
When Śrī Caitanya Mahāprabhu and His devotees approached him, they saw that he was covered with a deerskin. Seeing this, Śrī Caitanya Mahāprabhu became very unhappy.
Brahmānanda Bhāratī belonged to the Śaṅkara-sampradāya. (The title Bhāratī indicates a member of one of that sampradāya’s ten classes of sannyāsīs.) It is customary for a person who has renounced the world to cover his body with a deerskin or the bark of a tree. This is enjoined by the Manu-saṁhitā. But if a sannyāsī who has renounced the world simply wears a deerskin and does not spiritually advance, he is bewildered by false prestige. Śrī Caitanya Mahāprabhu did not like to see Brahmānanda Bhāratī wearing a deerskin.
