"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?"
"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
"The true rule of life is to guard and do by the things of others as they do by their own."
