You have seen the picture in TLC. Caitanya Mahāprabhu was at Allahabad, Prayāga, and Rūpa Gosvāmī met Him there. He was offering obeisances flat. You have seen that picture. So at that time Caitanya Mahāprabhu personally gave him instruction what is this cult of bhakti. So for ten days. And he took note of it and later on he placed this book in the form of Bhakti-rasāmṛta-sindhu. That is in Sanskrit. It will be difficult for you. Therefore I have presented a summary study, and the summary study has come to 407 pages. If we would have elaborately described each and every verse, then it would have come to at least thousand pages.
So the whole substance is creamed. You should take advantage of this. And don't indulge in much unnecessary talks. Time should be very properly utilized. Āyuṣaḥ kṣaṇa eko 'pi na labhyaḥ svarṇa-koṭibhiḥ. Value of time is so great that one moment of your life lost, it cannot be returned even in exchange of millions of dollars. Therefore every moment should be properly utilized. Avyartha kālatvam (Cc. Madhya 23.18-19). When one is advanced in Kṛṣṇa consciousness his business becomes to see, "Whether I am wasting my time?" That is one of the sign of advanced devotee.
