Shatakatraya 1.11

1.11

śakyo vārayituṃ jalena hutabhuk cchatreṇa sūryātapo
nāgendro niśitāgkuśena samado daṇḍena go-gardabhau |
vyādhir bheṣaja-saṅgrahaiś ca vividhair mantra-prayogair viṣaṃ
sarvasyauṣadham asti śāstra-vihitaṃ mūrkhasya nasty auṣadhim ||

Fire can be checked by water, the sun's heat by an umbrella,
a rutting elephant by a sharp goad, and a bull or donkey by a stick;
disease by collections of medicines and poison by various mantra-practices;
there is a remedy prescribed by authoritative treatises for everything, but there is no remedy for a fool.
