The Nawab did not like his retirement so he interned him, not allowed him to go out of home. But Rūpa Gosvāmī and his younger brother, Vallabha, they left home, and they left instruction also to Sanātana Gosvāmī, that there is some money for his release, he could utilize that money. So Rūpa Gosvāmī and Vallabha left home prior to Sanātana Gosvāmī's leaving home. So, Rūpa Gosvāmī and Vallabha met Lord Caitanya at Prayāga—these things are mentioned in our Teachings of Lord Caitanya—you can read, teachings to Sanātana Gosvāmī and Rūpa Gosvāmī and their meeting with Lord Caitanya at Allahabad, Prayāga.
So this boy, Jīva Gosvāmī, when he saw that his father and uncles all left home, why he should remain at home? So he also left, and he first of all went to Benares, which is called Vārāṇasī. It is a great center for learning Sanskrit. So he finished his education in Sanskrit grammar, specifically, he was a great scholar in Sanskrit grammar. According to Vedic system, the students are first of all taught the Sanskrit grammar, because it is very difficult subject.
Usually one has to study grammar for 12 years, and when one is very much conversant with grammatical rules, he can read any literature. That means after studying grammar, the door is open for any other subject matter, just like philosophy, medicine, then military art, there are so many Vedic knowledges. Generally they read literature, the Purāṇas, the Vedāntas and śaipa, śaipa means general literature. So Śrīla Jīva Gosvāmī became a great scholar in grammar and then he studied all Vedic literatures, and after that he approached his uncle Rūpa Gosvāmī in Vṛndāvana.
