Who is speaking and story frame
अन्तर्ह्रदे भुजगभोगपरीतमारात्
कृष्णं निरीहमुपलभ्य जलाशयान्ते ।
गोपांश्च मूढधिषणान् परित: पशूंश्च
सङ्क्रन्दत: परमकश्मलमापुरार्ता: ॥ १९ ॥

kṛṣṇaṁ nirīham upalabhya jalāśayānte
gopāṁś ca mūḍha-dhiṣaṇān paritaḥ paśūṁś ca
saṅkrandataḥ parama-kaśmalam āpur ārtāḥ

Seeing all this, the residents of Vṛndāvana were overwhelmed with anguish and confusion.
