रोहिणी च महाभागा नन्दगोपाभिनन्दिता ।
व्यचरद् दिव्यवासस्रक्कण्ठाभरणभूषिता ॥ १७ ॥
rohiṇī ca mahā-bhāgā
nanda-gopābhinanditā
vyacarad divya-vāsa-srak-
kaṇṭhābharaṇa-bhūṣitā
The most fortunate Rohiṇī, the mother of Baladeva, was honored by Nanda Mahārāja and Yaśodā, and thus she also dressed gorgeously and decorated herself with a necklace, a garland and other ornaments. She was busy wandering here and there to receive the women who were guests at the festival.
