Sri Caitanya-caritamrta

CC Adi-lila

Śrī Caitanya Mahāprabhu, Śrī Nityānanda Prabhu and Śrī Advaita Gosāñi Prabhu are natural gosvāmīs because They belong to the viṣṇu-tattva category. As such, all of Them are prabhus (“predominators” or “masters”), and They are sometimes called Caitanya Gosāñi, Nityānanda Gosāñi and Advaita Gosāñi.

CC Adi 7.13, Translation and Purport

Śrī Advaita Ācārya is Lord Caitanya’s incarnation as a devotee. Therefore these three tattvas [Caitanya Mahāprabhu, Nityānanda Prabhu and Advaita Gosāñi] are the predominators, or masters.

Gosāñi means gosvāmī. A person who has full control over the senses and mind is called a gosvāmī or gosāñi. One who does not have such control is called a godāsa, or a servant of the senses, and cannot become a spiritual master. A spiritual master who actually has control over the mind and senses is called Gosvāmī. Although the Gosvāmī title has become a hereditary designation for unscrupulous men, actually the title Gosāñi, or Gosvāmī, began from Śrī Rūpa Gosvāmī, who presented himself as an ordinary gṛhastha and minister in government service but became a gosvāmī when he was actually elevated by the instruction of Lord Caitanya Mahāprabhu. Therefore Gosvāmī is not a hereditary title but refers to one’s qualifications. When one is highly elevated in spiritual advancement, regardless of wherefrom he comes, he may be called Gosvāmī. Śrī Caitanya Mahāprabhu, Śrī Nityānanda Prabhu and Śrī Advaita Gosāñi Prabhu are natural gosvāmīs because They belong to the viṣṇu-tattva category. As such, all of Them are prabhus (“predominators” or “masters”), and They are sometimes called Caitanya Gosāñi, Nityānanda Gosāñi and Advaita Gosāñi. Unfortunately, Their so-called descendants who do not have the qualifications of gosvāmīs have accepted this title as a hereditary designation or a professional degree. That is not in accord with the śāstric injunctions.
