Grasping a red coal
The Buddha ( nickname = the awakened one ) said ~ 2500 years ago:
“Holding anger is like grasping a red coal with the intent of throwing it back at the source of your anger. You are the only one to get burn”.
“ Holding onto anger is like drinking poison and expecting the other person to die.”
“ Anger is a feeling which makes our mouth working faster than our mind.”
Ven. Ji Gong Sunim.
