gopyaḥ - the gopīs; tat - of Them; gītam - the singing; ākarṇya - hearing; mūrcchitāḥ - stunned; na avidan - were not aware of; nṛpa - my dear King; sraṁsat - slipping; dukūlam - the fine cloth of their garments; ātmānam - themselves; srasta - disheveled; keśa - their hair; srajam - the garlands; tataḥ - (slipping) from that.

The gopīs became stunned when they heard that song. Forgetting themselves, O King, they did not notice that their fine garments were becoming loose and their hair and garlands disheveled.
