The Hundred Verses of Amaru 1.137

1.137

adyārabhya yadi priye punarahaṃ mānasya vā'nyasya vā
gṛhṇīyāṃ śaṭhadurnayena manasā nāmāpi saṃkṣepataḥ |
tattenaiva vinā śaśāṅkadhavalāḥ spaṣṭāṭṭahāsā niśā
eko vā divasaḥ payodamalino yāyānmama prāvṛṣi ||99||(93)

Starting today, if I ever, through a mind set on crooked wickedness,
even briefly utter the name of amorous petulance or of another towards my beloved,
then without him may moon-white nights with loud laughter pass for me,
or even a single day darkened by rain clouds in the monsoon. ||99||(93)
