Lord Caitanya’s acceptance of Sannyāsa

This tract of land, Navadvīpa, is the place of highly educated brāhmaṇas from time immemorial. So Śrī Caitanya Mahāprabhu belonged to a very respectable brāhmaṇa family, the son of Jagannātha Miśra; His grandfather, Nīlāmbara Cakravartī. Very respectful, respectable persons. He took birth in that family. Personally He was very beautiful; therefore His another name is Gaurasundara. And He was very learned scholar also; therefore His another name is Nimāi Paṇḍita. So . . . and in His family life He had very nice, beautiful young wife, Viṣṇupriyā, and very affectionate mother, and He was very influential. You know that. In one day He collected about one hundred thousand followers to protest against the Kazi’s order. So in this way His social position was very favorable. Personal position was very favorable. Still, He took sannyāsa, left home. Why? Dayitaye: in order to favor, in order to show mercy to the fallen souls of the world.
So He left a legacy that anyone who has taken birth in India,
bhārata-bhūmite manuṣya-janma haila yāra
janma sārthaka kari’ kara para-upakāra
(CC Adi 9.41)
So He exhibited personally how to do para-upakāra, welfare to others, fallen souls. So this sannyāsa means following the order of Śrī Caitanya Mahāprabhu that,
āmāra ājñāya guru hañā tara’ ei deśa
yāre dekha tāre kaha ‘kṛṣṇa’-upadeśa
(CC Madhya 7.128)
So not only . . . we are trying to create a position that not only the Indians have got this responsibility, but according to Śrī Caitanya Mahāprabhu, anyone—pṛthivīte āche yata nagarādi grāma (CB Antya-khaṇḍa 4.126)—they should take up this missionary work. And I am so much obliged to you, you American boys and girls also, that you have taken this Kṛṣṇa consciousness movement very seriously.

At the end of His twenty-fourth year, in the month of Māgha, Śrī Caitanya Mahāprabhu accepted the sannyāsa order during the waxing period of the moon.
(CC Madhya 3.3)

After saying this, Keśava Bhāratī, the spiritual master, went back to his village, Katwa. Lord Caitanya Mahāprabhu went there and accepted the renounced order of life [sannyāsa].
PURPORT
At the end of His twenty-fourth year, at the end of the fortnight of the waxing moon, Śrī Caitanya Mahāprabhu left Navadvīpa and crossed the river Ganges at a place known as Nidayāra-ghāṭa. Then He reached Kaṇṭaka-nagara, or Kāṭoyā (Katwa), where He accepted ekadaṇḍa-sannyāsa according to the Śaṅkarite system. Since Keśava Bhāratī belonged to the Śaṅkarite sect, he could not initiate Caitanya Mahāprabhu into the Vaiṣṇava sannyāsa order, whose members carry the tridaṇḍa.
(CC Adi 17.272)

Before disclosing His desire to take the renounced order of life, Lord Caitanya first went to the house of Mukunda Datta, but at that time Mukunda Datta requested Lord Caitanya Mahāprabhu to continue His saṅkīrtana movement for a few days more before taking sannyāsa. This is stated in the Caitanya-bhāgavata, Madhya-khaṇḍa, Chapter Twenty-six. The information of Lord Caitanya’s accepting the renounced order was made known to Gadādhara Paṇḍita, Candraśekhara Ācārya and Mukunda Datta by Nityānanda Prabhu, and therefore all of them went to Katwa and arranged for kīrtana and all the paraphernalia for Lord Caitanya’s acceptance of sannyāsa. After the Lord took sannyāsa, they all followed Him, especially Śrī Nityānanda Prabhu, Gadādhara Prabhu and Mukunda Datta, who followed Him all the way to Puruṣottama-kṣetra. In this connection one may refer to Śrī Caitanya-bhāgavata, Antya-khaṇḍa, Chapter Two. In the place known as Jaleśvara, Nityānanda Prabhu broke the sannyāsa rod of Caitanya Mahāprabhu (CC Madhya 1.97). Mukunda Datta was also present at that time. He went every year from Bengal to see Lord Caitanya at Jagannātha Purī.
(CC Adi 10.40 purport)

When Śrī Caitanya Mahāprabhu decided to accept the renounced order of life, Candraśekhara Ācārya was informed of this by Śrī Nityānanda Prabhu, and therefore he was present when Lord Caitanya accepted sannyāsa from Keśava Bhāratī in Katwa. It is he who first spread the word in Navadvīpa of Lord Caitanya’s accepting sannyāsa. Śrī Candraśekhara Ācārya was present during many important incidents in the pastimes of Lord Caitanya Mahāprabhu. He therefore forms the second branch of the tree of Lord Caitanya.
(CC Adi 10.13 purport)

In the Gaura-gaṇoddeśa-dīpikā (52), it is said:

mathurāyāṁ yajña-sūtraṁ purā kṛṣṇāya yo muniḥ

dadau sāndīpaniḥ so ’bhūd adya keśava-bhāratī

“Sāndīpani Muni, who formerly offered the sacred thread to Kṛṣṇa and Balarāma, later became Keśava Bhāratī.” It is he who offered sannyāsa to Śrī Caitanya Mahāprabhu. There is another statement about Keśava Bhāratī from the Gaura-gaṇoddeśa-dīpikā (117): iti kecit prabhāṣante ’krūraḥ keśava-bhāratī. “According to some authoritative opinions, Keśava Bhāratī is an incarnation of Akrūra.” Keśava Bhāratī offered the sannyāsa order to Śrī Caitanya Mahāprabhu in the year 1432 śakābda (A.D. 1510) in Katwa. This is stated in the Vaiṣṇava-mañjuṣā, Part Two.
