dui bhāi hṛdayera kṣāli' andhakāra
dui bhāgavata-saṅge karāna sākṣātkāra
dui—two; bhāi—brothers; hṛdayera—of the heart; kṣāli'-purifying; andhakāra—darkness; dui bhāgavata—of the two bhāgavatas; saṅge—by the association; karāna—cause; sākṣāt-kāra—a meeting.
But these two brothers [Lord Caitanya and Lord Nityānanda] dissipate the darkness of the inner core of the heart, and thus They help one meet the two kinds of bhāgavatas [persons or things in relationship with the Personality of Godhead].
