ITRANS:
tāṁs tathaivāvṛtān śigbhirmṛtyu-grastān viceṣṭataḥsvayaṁ ca kṛpaṇaḥ śikṣupaśyann apy abudho ’patat
Translation:
As the father pigeon wretchedly stared at his poor children trapped in the net and on the verge of death, pathetically struggling to free themselves, his mind went blank, and thus he himself fell into the hunter’s net.
