I've explained to you that there are ten different names in the Śaṅkara-sampradāya of the sannyāsī, and there are 108 names amongst the Vaiṣṇava sannyāsa. So Caitanya Mahāprabhu, although He was initiated by Vaiṣṇava, He took sannyāsa, He accepted sannyāsa, from Bhāratī, who belongs to the Śaṅkara-sampradāya, Śaṅkara sect.
The rule is that if one has to accept renounced order of life, there is ceremony. As there is ceremony of initiation, there is ceremony of accepting this renounced order of life. And that ceremony must be performed by another bona fide, I mean to . . . sannyāsī, renounced order. It is not that you take your cloth and get it colored and one day you become a sannyāsī. No. There are ceremonies.
