“A man should not hate any living creature. Let him be friendly and compassionate to all. He must free himself from the delusion of ‘I’ and ‘mine.’ He must accept pleasure and pain with equal tranquillity. He must be forgiving, ever-contented, self-controlled, united constantly… in his meditation. His resolve must be unshakable. He must be dedicated… in intellect and in mind.”
The Bhagavad-Gita
