"The best type of yogi is he who feels for others, whether in grief or pleasure, even as he feels for himself."
"Do not to others what ye do not wish done to yourself; and wish for others too, what ye desire and long for, for yourself. This is the whole of Dharma, heed it well."
Bhagavad Gita, 2:65
"A superior being does not render evil for evil... One should never harm the wicked or the good or even criminals meriting death. A noble soul will ever exercise compassion even toward those who enjoy injuring others - for who is without fault?"
