Pradyumna: "It is only for our guidance that Śrīla Rūpa Gosvāmī prepared this book, the Bhakti-rasāmṛta-sindhu, which is now presented in the form of The Nectar of Devotion. Persons engaged in the Kṛṣṇa consciousness movement may take advantage of this great literature and be very solidly situated in Kṛṣṇa consciousness. Bhakti means devotional service. Every service has some attractive feature which drives the servitor progressively on and on. Every one of us within this material world..."
Prabhupāda: Without, without some attractive feature, nobody is interested. Just like we are talking here about Kṛṣṇa-bhakti, but people in general, they're not very much attracted to Kṛṣṇa consciousness. So they do not care to come. There must be some attractive feature. Otherwise... So different people have got different attractive features.
