उपदेशो हि मूर्खानां प्रकोपाय न शान्तये ।
पयःपानं भुजन्गानां केवलं विषवर्धनम् ॥
upadeśo hi mūrkhānāṁ prakopāya na śāntaye |
payaḥ-pānaṁ bhujangānāṁ kevalaṁ viṣa-vardhanam ||
(Pañcatantra: 1.420)
“Advice leads [only] to angering fools, not pacifying them. Drinking milk only increases the poison of snakes.”
