Bhakti-rasāmṛta-sindhu .3.55
Blended reading (Sanskrit + English inline)
If someone becomes attached to the principles of salvation or to merging into the existence of the brahma-jyoti, his ecstasies gradually diminish into shadow and parā attachment or else transform into the principles of ahaṅgrahopāsanā. This ahaṅgrahopāsanā describes a living entity when he begins spiritual realization by identifying himself with the Supreme Lord. This state of self-realization is technically known as monism. The monist thinks himself one with the Supreme Lord. Thus, because he does not differentiate between himself and the Supreme Lord, it is his view that by worshiping himself he is worshiping the supreme whole.
By intimate association with a person desiring liberation, who is fixed in that philosophy and who uses logic from jñāna scriptures which establish the superiority of liberation over everything else (supratiṣṭhite), real bhāva becomes bhāvābhāsa. Alternatively, he identifies himself with the Lord who is worthy of worship. This becomes self-worship.
Bhajanīyeśa-bhāvatām means identifying oneself as the Lord, who is the actual object of worship. Bhāva for the Lord becomes ahaṅgrahopāsanām, worship of the self.
