tasmād dharma-pradhānena
tasmād dharma-pradhānena bhavitavyaṁ yatātmanā |
tathā ca sarva-bhūteṣu vartitavyaṁ yathātmani ||
(Mahābhārata: 12.161.8)
[Vidura to Yudhiṣṭhira:] “Therefore, with dharma as one’s chief object, one should be self-controlled. And one should treat all beings as oneself [i.e., one should treat others as one would treat oneself].”
