उपकारिषु यः साधुः साधुत्वे तस्य को गुणः ।
अपकारिषु यः साधुः स साधुः सद्भिरुच्यते ॥
upakāriṣu yaḥ sādhuḥ sādhutve tasya ko guṇaḥ |
apakāriṣu yaḥ sādhuḥ sa sādhuḥ sadbhir ucyate ||
(Mahāsubhāṣita-saṅgraha: 7031)
“What sort of quality is the goodness of one who is good [only] to those who are helpful [to oneself]? One who is good [even] to those who are harmful [to oneself] is said to be good [i.e., a sādhu] by the wise.”
