PURPORT

Everyone has a particular transcendental mellow by which he loves and serves Krsna. Krsna is the most attractive feature for every kind of devotee. He is therefore called akhila-rasamrta-murti, the transcendental form of attraction for all kinds of devotees, whether the devotee be in the santa-rasa, dasya-rasa, sakhya-rasa, madhurya-rasa or vatsalya-rasa.

This is the opening verse of Bhakti-rasamrta-sindhu by Srila Rupa Gosvami.
