Everyone has a particular transcendental mellow by which he loves and serves Kṛṣṇa. Kṛṣṇa is the most attractive feature for every kind of devotee. He is therefore called akhila-rasāmṛta-mūrti, the transcendental form of attraction for all kinds of devotees, whether the devotee be in the śānta-rasa, dāsya-rasa, sakhya-rasa, vātsalya-rasa or mādhurya-rasa.
This is the opening verse of the Bhakti-rasāmṛta-sindhu, by Śrīla Rūpa Gosvāmī.
