So bhakti-rasāmṛta-sindhu is to taste the mellow of serving Kṛṣṇa. That is the science of serving Kṛṣṇa. Therefore we have named this book, "Nectar of Devotion." It is summary study of bhakti-rasa, the mellow, the transcendental mellow which one can taste. Everyone is tasting. Otherwise he cannot work. So yat karoṣi yaj juhoṣi. Kṛṣṇa says, "Whatever engagement you may have, kuruṣva tad mad-arpaṇam, do it for Kṛṣṇa." Don't take the result yourself. Give it to Kṛṣṇa. Then you'll taste the rel..., relish the mellow, transcendental mellow, bhakti-rasa. And then you'll be happy.
Just like about the Gosvāmīs, Rūpa Gosvāmī, who was executing his devotional service on this spot... They were ministers. And they gave up everything. Tyaktvā tūrṇam aśeṣa-maṇḍala-pati-śreṇīm. Maṇḍala-pati. Maṇḍala-pati means leaders. The leader of the group, maṇḍala-pati. Just like there is rastra-pati. Similarly they were rastra-patis, maṇḍala-pati, but tyaktvā tūrṇam aśeṣa-maṇḍala-pati... Because they were minister, their friendly circles were big, big zamindars, administrators. But they gave up their company. Tyakvtā tūrṇam aśeṣa-maṇ... Not one, two, but many. Tyaktvā tūrṇam aśeṣa-maṇḍala-pati-śreṇīṁ sadā tucchavat. Very insignificant. "Oh, what is this? Give up." Bhūtvā dīna-gaṇeśakau karuṇayā kaupīna-kanthāśritau. Became very poor mendicants, accepted torn cloth. Sanātana Gosvāmī, Rūpa Gosvāmī, here, in Vṛndāvana, they were living underneath one tree, one night. Such vairāgya, renunciation. But how they were living? A very rich man, coming to the lowest standard of living...
