I shall speak in a condensed form, for rasa is not susceptible of elaborate description since rasa can only be understood thorugh insight and deep realisation. The ocean of the mellow of Bhakti is profound and devoid of bounding shores. The specific nature of the jiva is infinitessimal in magnitude like the hundredth part of the tip of a hair. The jivas are divided into two distinct groups, viz. The moving jivas are again divided into those who live on the land, in water and in the air.
Mankind is a very small part of the total number of jivas that live on the land.
They commit many sins forbidden by the Veda and do not really care for that religion. Then again, among those who really act in accordance with that religion, most persons are addicted to fruitive activities. It is rarely that any fortunate jiva, in the course of his wanderings in this mundane world, may obtain a chance to come to know Bhakti. That is, it is rare for someone to obtain the seed of the creeper of Bhakti, which is only found by the favour of Guru and Krishna. Bhakti grows like a creeper growing from a tiny seed.
