After His sannyāsa, He was induced to visit the house of Advaita Prabhu in Śāntipura. Advaita managed to invite all His friends and admirers from Nadia and brought Śacīdevī to see her son. Both pleasure and pain invaded her heart when she saw her son in the attire of a sannyāsī. As a sannyāsī, Kṛṣṇa Caitanya put on nothing but a kaupīna and a bahirvāsa (outer covering). His head was without hair, and His hands bore a daṇḍa (stick) and a kamaṇḍalu (hermit's waterpot).
The holy son fell at the feet of His beloved mother and said, "Mother! This body is yours, and I must obey your orders. Permit Me to go to Vṛndāvana for My spiritual attainments." The mother, in consultation with Advaita and others, asked her son to reside in Purī (the town of Jagannātha) so that she might obtain news of Him now and then. Mahāprabhu agreed to that proposition and in a few days left Śāntipura for Orissa.
His biographers have described the journey of Kṛṣṇa Caitanya (that was the name He got after His sannyāsa) from Śāntipura to Purī in great detail. He traveled along the side of the Bhāgīrathī as far as Chatrabhoga, situated now in Thānā Mathurāpura, Diamond Harbor, Twenty-four Parganas. There He took a boat and went as far as Prayāga-ghāṭa, in the Midnapura District. Thence He walked through Balasore and Cuttack to Purī, seeing the temple of Bhūvaneśvara on His way. Upon His arrival at Purī He saw Jagannātha in the temple and resided with Sārvabhauma at the request of the latter.
Sārvabhauma was a gigantic paṇḍita of the day. His readings knew no bounds. He was the best naiyāyika of the times and was known as the most erudite scholar in the Vedānta philosophy of the school of Śaṅkarācārya. He was born in Nadia (Vidyānagara) and taught innumerable pupils in the nyāya philosophy in his tola there. He had left for Purī some time before the birth of Nimāi Paṇḍita. His brother-in-law Gopīnātha Miśra introduced our new sannyāsī to Sārvabhauma, who was astonished at His personal beauty and feared that it would be difficult for the young man to maintain sannyāsa-dharma during the long run of His life. Gopīnātha, who had known Mahāprabhu from Nadia, had a great reverence for Him and declared that the sannyāsī was not a common human being. On this point Gopīnātha and Sārvabhauma had a hot discussion. Sārvabhauma then requested Mahāprabhu to hear his recitation of the Vedānta-sūtras, and the latter tacitly submitted.
Caitanya heard with silence what the great Sārvabhauma uttered with gravity for seven days, at the end of which the latter said, "Kṛṣṇa Caitanya! I think You do not understand the Vedānta, for You do not say anything after hearing my recitation and explanations."
