A Brahman asked the Buddha, “Master, is there anything you would agree to kill?”
The Buddha answered, “Yes, anger. Killing anger removes suffering and brings peace and happiness.”
We “kill” our anger by smiling to it, holding it gently, looking deeply to understand its roots and transforming it with understanding and compassion.
The Buddha’s response so impressed the man, he became a monk.
When his cousin learned of this, he cursed the Buddha to his face. The Buddha only smiled.
The cousin became even more incensed and asked, “Why don’t you respond?” The Buddha replied, “If someone refuses a gift, it must be taken back by the one who offered it.”
Angry words and actions hurt oneself first and hurt oneself most of all.
