In Bhakti-rasāmṛta-sindhu (1.3.1) the state of being in love with the Godhead is compared to the sunshine emanating from the sun; this shining makes the devotee's heart more and more lovely. The heart of such a devotee is situated in a transcendental position beyond even the mode of goodness. The process for making the heart even more sterilized by the sunshine of love is called bhāva. A description of bhāva is given by Rūpa Gosvāmī. Bhāva is called the permanent characteristic of the living entity, and the crucial point of progress for bhāva is called the marginal state of love of Godhead. When the bhāva state becomes deeper and deeper, learned devotees call it love of Godhead. As stated in the Nārada-pañcarātra:
- ananya-mamatā viṣṇau
- mamatā prema-saṅgatā
- bhaktir ity ucyate bhīṣma-
- prahlādoddhava-nāradaiḥ
"When one is firmly convinced that Viṣṇu is the only object of love and worship and that there is no one else—not even a demigod—worthy of receiving devotional service, one feels intimacy in his love relationship with God, and this is approved by such personalities as Bhīṣma, Prahlāda, Uddhava and Nārada."
