labheta sikatāsu tailam api yatnataḥ pīḍayan
pibec ca mṛga-tṛṣṇikāsu salilaṃ pipāsārditaḥ |
kvacid api paryaṭan śaśa-viṣāṇam āsādayet
na tu pratiniviṣṭa-mūrkha-cittam ārādhayet ||

one tormented by thirst might even drink water from mirages,
wandering somewhere one might even find a hare's horn,
but one cannot win over the mind of an obstinate fool.
