The female guards eventually noticed unmistakable symptoms of romantic involvement in Ūṣā, who, having broken her maiden vow, was being enjoyed by the Yadu hero and showing signs of conjugal happiness. The guards went to Bāṇāsura and told him, “O King, we have detected in your daughter the kind of improper behavior that spoils the reputation of a young girl’s family.

Śrīla Viśvanātha Cakravartī has defined the word bhaṭāḥ as “female guards,” whereas Jīva Gosvāmī defines it as “eunuchs and others.” Grammatically, the word can function both ways.

The guards feared that if Bāṇāsura found out about Ūṣā’s activities from some other source, he would severely punish them, and thus they personally informed him that his young daughter was no longer innocent.
