In The Kodhana Sutta, the blessed one descibes the damage that anger does to ourselves and others.
A angry person in this Sutta is described as “in a mass of darkness”.
The flame consumes the mind of a individual, burning himself and those around him.
He is then blotted out left with a smoke of despair.
The Kodhana Sutta Reads:
An angry person is ugly & sleeps poorly.
Gaining a profit, he turns it into a loss, having done damage with word & deed.
A person overwhelmed with anger destroys his wealth.
Maddened with anger, he destroys his status.
Relatives, friends, & colleagues avoid him.
Anger brings loss.
Anger inflames the mind.
He doesn’t realize that his danger is born from within.
An angry person doesn’t know his own benefit.
An angry person doesn’t see the Dhamma.
A man conquered by anger is in a mass of darkness.
He takes pleasure in bad deeds as if they were good, but later, when his anger is gone, he suffers as if burned with fire.
He is spoiled, blotted out, like fire enveloped in smoke.
When anger spreads, when a man becomes angry, he has no shame, no fear of evil, is not respectful in speech.
For a person overcome with anger, nothing gives light.
I’ll list the deeds that bring remorse, that are far from the teachings.
An angry person kills his father, kills his mother,
kills Brahmans & people run-of-the-mill.
It’s because of a mother’s devotion that one sees the world, yet an angry run-of-the-mill person can kill this giver of life.
Like oneself, all beings hold themselves most dear, yet an angry person, deranged, can kill himself in many ways: with a sword, taking poison, hanging himself by a rope in a mountain glen.
Doing these deeds that kill beings and do violence to himself, the angry person doesn’t realize that he’s ruined.
This snare of Mara, in the form of anger, dwelling in the cave of the heart: cut it out with self-control, discernment, persistence, right view.
The wise man would cut out each & every form of unskillfulness.
Train yourselves: ‘May we not be blotted out.’
Free from anger & untroubled, free from greed, without longing, tamed, your anger abandoned,
free from fermentation, you will be unbound.
