The Hundred Verses of Amaru 1.203

1.203

bhrūbhaṅge racite'pi dṛṣṭiradhikaṃ sotkaṇṭhamudvīkṣate
kārkaśyaṃ gamite'pi cetasi tanūromāñcamālambate |
ruddhāyāmapi vāci sasmitamidaṃ dagdhānanaṃ jāyate
dṛṣṭe nirvahaṇaṃ bhaviṣyati kathaṃ mānasya tasmiñjane ||24||(28)

Even when a frown is formed, my gaze looks up with still greater longing;
even when my mind is hardened, my body breaks into horripilation;
even when speech is withheld, this wretched face breaks into a smile:
when that man is seen, how can amorous petulance be sustained? ||24||(28)
