Our mission is to establish the desire of Śrī Caitanya Mahāprabhu. That is our business. Śrī-caitanya-mano-'bhīṣṭaṁ sthāpitaṁ yena bhū-tale. Śrīla Rūpa Gosvāmī did it. He has given us so many books, especially Bhakti-rasāmṛta-sindhu, which we have translated into English as Nectar of Devotion, to understand the science of devotional service. This is the greatest contribution of Śrīla Rūpa Gosvāmī: how to become a devotee. How to become a devotee. It is not sentiment; it is science. This Kṛṣṇa consciousness movement is a great science. Yad vijñāna-samanvitam. Jñānaṁ me paramaṁ guhyaṁ yad vijñāna-samanvitam (SB 2.9.31). It is not sentiment. If you take it as sentiment, then you will create disturbance. That is the instruction of Rūpa Gosvāmī.
