असद्भिः शपथेनोक्तं जले लिखितमक्षरम् ।
सद्भिस्तु लीलया प्रोक्तं शिलालिखितमक्षरम् ॥
asadbhiḥ śapathenoktaṁ jale likhitam akṣaram |
sadbhis tu līlayā proktaṁ śilā-likhitam akṣaram ||
(Subhāṣita-ratna-bhāṇḍāgāra)
“The words [even] under oath of the wicked are like letters written on water [i.e., completely insubstantial]. The [even] playful words of sādhus, however, are like words written in stone [i.e., they certainly prove truthful].”
