Caitanya-caritāmṛta 20.46
sei bhāve prabhu sei śloka uccārilā śloka uccārite tad-rūpa āpane ha-ilā
[sei bhaave prabhu sei shloka uchchaarilaa shloka uchchaarite tad-roopa aapane ha-ilaa]
Blended reading (Sanskrit + English inline)
sei bhāve prabhu sei śloka uccārilā śloka uccārite tad-rūpa āpane ha-ilā
In the same spirit of ecstasy, Śrī Caitanya Mahāprabhu recited that verse, and as soon as He did so, He felt like Śrīmatī Rādhārāṇī.
