By the order of Lord Caitanya they went to Vṛndāvana, and the present city of Vṛndāvana is the contribution of the Gosvāmīs. First of all Sanātana Gosvāmī went there, then Rūpa Gosvāmī. In this way the city was excavated. It was formerly, five hundred years ago, there was no trace where and how Kṛṣṇa līlā was performed in that tract of land. But when Caitanya Mahāprabhu went there, He first of all discovered Rādhā-kuṇḍa, the lake in which Śrīmatī Rādhārāṇī used to take bath and Kṛṣṇa used to come. There is Śyāma-kuṇḍa also. The Śyāma-kuṇḍa, Rādhā-kuṇḍa, two lakes are still existing. Hundreds . . . thousands of people, devotees, go to see that lake every day.
So the six Gosvāmīs were . . . some of them were very prominent government officers. Just like Rūpa Gosvāmī and Sanātana Gosvāmī: they were two important ministers in the then-Muhammadan government, Nawab Hussain Shah, his government. They resigned their ministerial post and joined Sri Caitanya Mahāprabhu for propagating His mission of Kṛṣṇa consciousness. So rūpa-sanātanau, they are very responsible government officers.
And raghu-yugau, raghu-yugau, two Raghunātha: one Raghunātha Bhaṭṭa and one Raghunātha dāsa. Raghunātha dāsa was the only son of his father and uncle, very big landholder of Bengal. Their father's income was twelve hundred thousands of rupees in those days. Now you can increase at least fifty times and then calculate what was the income of Raghunātha dāsa Gosvāmī. But he left everything to join Caitanya Mahāprabhu's movement.
Gopāla Bhaṭṭa Gosvāmī also came from a very learned brahmin family. Similarly, Jīva Gosvāmī was the greatest scholar till now. Nobody can compete with Jīva Gosvāmī's scholarship in Sanskrit and philosophy. That is the verdict of all learned scholars. The world's best philosopher and Sanskrit scholar was Śrīla Jīva Gosvāmī. He happened to be the nephews of Rūpa Gosvāmī.
When Jīva Gosvāmī's father and uncles left home, he was only ten-years-old boy. He thought, "If my father and uncles have left, why shall I not leave home?" So at the age of ten years he left home and went to Benares, the seat of Sanskrit scholars. He learned there Sanskrit very nicely, became a very great scholar, and then joined their uncles in Vṛndāvana. Of course, at that time Caitanya Mahāprabhu had passed. So Jīva Gosvāmī, he is also very learned scholar. His books are still adored by all spiritual sections. Sandarbas, six sandarbas, philosophical theses.
And then vande rūpa-sanātanau raghu-yugau śrī-jīva-gopālakau. Gopāla Bhaṭṭa Gosvāmī, he was also learned scholar. So all rich men, rich politicians, scholars, great brahmins, they joined Caitanya Mahāprabhu. It is so nice movement. It attracted thousands of people, just (as) it is attracting you, American boys and girls.
So in those days, a scholarly section, learned section, rich section were attracted by Caitanya Mahāprabhu's movement. And what was their business? This business, as you are doing: kṛṣṇa kīrtana-gāna-nartana-parau (Śrī Ṣaḍ-gosvāmy-aṣṭaka 1). Their engagement was kṛṣṇa ut kīrtanam. Kṛṣṇa kīrtanam, singing about Kṛṣṇa, just like you are doing—Hare Kṛṣṇa. Kṛṣṇa ut-kīrtana, very loudly chanting Hare Kṛṣṇa, Hare Kṛṣṇa, kṛṣṇot-kīrtana-gāna, and sometimes prayer, songs. Nartana. Naratana means dancing. These were their engagement: kṛṣṇot-kīrtana-gāna-nartana-parau premāmṛtāmbho-nidhī. And as soon as they chanted, immediately they were immersed in the ocean of bliss, prema, ecstasy of love of God, Kṛṣṇa.
