By reading Vedic literature, you enlighten yourself with knowledge. So this is also yajña. There are so many . . . Kṛṣṇa is available in so many ways, according to your position. It is not that He is conditioned. He is not conditioned. Therefore it is called ahaituky apratihatā. The svādhyāya-yajña.
The Gosvāmīs, they were not only dancing and chanting. That was also part of their business, kṛṣṇotkīrtana-gāna-nartana-parau. But they were also good scholars. Nānā-śāstra-vicāraṇaika-nipuṇau sad-dharma-saṁsthāpakau. Just like in our Kṛṣṇa consciousness movement, we are trying to publish our books in different languages. Already we have got in European and American, English, French, German, Spanish, Swedish, Japanese, Chinese. This is required.
Nānā-śāstra-vicāraṇaika-nipuṇau sad-dharma. Because people are misled. So they should be given opportunity to study, to understand what is God consciousness, what is Kṛṣṇa consciousness. So through the śāstras. That is also required. Nānā-śāstra-vicāraṇaika-nipuṇau sad-dharma . . . the Gosvāmīs practically demonstrated in their life everything. Caitanya Mahāprabhu taught them. They were the first disciples of Śrī Caitanya Mahāprabhu. Rūpa Gosvāmī was given lesson for ten days continually at Allahabad, Prayāga, Daśāśvamedha-ghāṭa. As a result of his instruction, he first wrote this Bhakti-rasāmṛta-sindhu, which we have translated into English, Nectar of Devotion. Similarly, Sanātana Gosvāmī was given instruction for two months at Benares, Vārāṇasī.
So bhakti is not that it is something sentiment, without any basic principle of knowledge. No. It is fully based on Vedic knowledge. Bhaktyā śruta-gṛhītayā. Śruta. Śruta means Veda. Bhakti, after studying the Vedic knowledge—that is perfect bhakti. Vedānta-sūtra.
