Caitanya-caritāmṛta 17.50
bhāva-śābalye rādhāra ukti, līlā-śuke haila sphūrti, sei bhāve paḍe eka śloka unmādera sāmarthye, sei ślokera kare arthe, yei artha nāhi jāne loka
[bhaava-shaabalye raadhaara ukti, leelaa-shuke haila sphoorti, sei bhaave pade eka shloka unmaadera saamarthye, sei shlokera kare arthe, yei artha naahi jaane loka]
Blended reading (Sanskrit + English inline)
bhāva-śābalye rādhāra ukti, līlā-śuke haila sphūrti, sei bhāve paḍe eka śloka unmādera sāmarthye, sei ślokera kare arthe, yei artha nāhi jāne loka
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.
