He is very sympathetic with the fallen souls of this age. He understands that these people, these conditioned souls, cannot execute the regular process of perfection. Therefore He has bestowed His benediction that you simply chant Hare Kṛṣṇa and be perfect. That is the saṅkīrtana movement. But kaścid—therefore although it is meant for a particular person out of many thousands of millions of persons, but still, by the blessings of Lord Caitanya, anyone can take it up. Anyone. It is freely being distributed. So kecit kevalayā bhaktyā. Śukadeva Goswāmī recommends that somebody takes to this bhakti-yoga process, kevalayā-bhakta. Bhakta means bhakti-yoga. Kevalayā. Kevalayā means without any adulteration. Just like if I say "only milk," that means without any water, without any adulteration: "only this." "Only" means kevalayā; "only." "Only" means pure, the pure of bhakta, pure devotional service.
There are impure and pure everything; similarly this devotional service is pure and impure also. What is pure and impure? What is pure? That definition you will find in our Nectar of Devotion. That definition is anyābhilāṣitā-śūnyaṁ (Bhakti-rasāmṛta-sindhu 1.1.11):
without any motive. Just like we sometimes go to God . . . naturally, generally you go to temple or church with a motive: "God, give us our daily bread." Or the Hindus or the Muslims they also go, "My dear Lord, I am in distress. Please give me relief." That is natural; there is a motive. But that, when one approaches God with a motive, that is not kevala; that is impure, when there is motive. Motiveless. One should approach God simply out of love; that is kevala bhakta, kevalayā bhaktyā.
