अव्याकरणमधीतं भिन्नद्रोण्या तरङ्गिणीतरणम् ।
भेषजमपथ्यसहितं त्रयमिदमकृतं वरं न कृतम् ।।
avyākaraṇamadhītaṃ bhinnadroṇyā taraṅgiṇītaraṇam |
bheṣajamapathyasahitaṃ trayamidamakṛtaṃ varaṃ na kṛtam ||
Three things are better not done rather than done : learning which has no foundation of grammar, the crossing of a river in a boat that leaks, and the use of medicines along with unwholesome diet.
