Rādhā is here the typical Proshita-preyasī 'whose husband has gone abroad, appointing a time of return' (Keśava Dāsa).
The poet says that Rādhā should have thought before she drank. To take water from a man of low caste is to 'lose caste'—but it is too late to think of this after the water is already drunk.
The idea of reproach is essential to the drama of the soul, and a leading motif of the greater part of Rādhā-Krishna literature:
'Folk, family, house and husband are abandoned, the reproach of the world rejected.'
Prema Sāgara.
