Bhagavad Gita 11.29

As moths impetuously fly towards the flame, only to be killed, so these men rush into Your mouths to court their own destruction.

यथा प्रदीप्तं ज्वलनं पतङ्गा
विशन्ति नाशाय समृद्धवेगाः।
तथैव नाशाय विशन्ति लोका
स्तवापि वक्त्राणि समृद्धवेगाः॥

yathā pradīptaṃ jvalanaṃ pataṅgā
viśanti nāśāya samṛddhavegāḥ|
tathaiva nāśāya viśanti lokā
stavāpi vaktrāṇi samṛddhavegāḥ||
