Translation: 
The aggregate of all these ecstasies once awoke a statement by Śrīmatī Rādhārāṇī in the mind of Bilvamaṅgala Ṭhākura [Līlā-śuka]. In the same ecstatic mood, Śrī Caitanya Mahāprabhu now recited that verse, and on the strength of madness He described its meaning, which is unknown to people in general.
