CC Madhya 10.160

āji haite nā pariba ei carmāmbara
prabhu bahirvāsa ānāilā jāniyā antara
Word for word: 
āji haite — from today; nā pariba — I shall not put on; ei — this; carma-ambara — deerskin garment; prabhu — Śrī Caitanya Mahāprabhu; bahir-vāsa — the cloth of a sannyāsī; ānāilā — had someone bring; jāniyā — knowing; antara — his contemplation.
Translation: 
“From today on I shall not wear this deerskin.” As soon as Brahmānanda Bhāratī decided this, Śrī Caitanya Mahāprabhu, understanding his mind, immediately sent for the robes of a sannyāsī.
