In Buddhism, there are many methods to deal with anger.
The method of accepting anger is a method of 'non-conflict'. By fully acknowledging & accepting anger in an open way, you can develop some objectivity towards & independence from the anger (in that it will not control your behaviour) and, importantly, give anger the space to subside.
The method I personally prefer & the method most used by the Buddha before his enlightenment was to wisely reflect (think about) the harm & dangers of anger; in how anger can harm yourself & harm others.
If you are often habitually & uncontrollably angry:
(1) You feel bad about yourself (afterwards).
(2) You become tense & can harm the health of your body & mind.
(3) People may dislike, fear or avoid you.
(4) Important relationships can be harmed, broken & lost.
(5) You can lose your job (employment) & develop a bad reputation.
The scriptures state:
As I abided...a thought of ill will (anger) arose in me. I understood thus: ‘This thought of anger has arisen in me. This leads to my own
affliction (harm), to others’ affliction and to the affliction of
both; it obstructs wisdom, causes difficulties (vexation) and leads
away from peace.‘ When I considered thus…it subsided in me. Whenever a
thought of anger arose in me, I abandoned it, removed it, did away
Just as in the last month of the rainy season, in the autumn, when the crops thicken, a cowherd would guard his cows by constantly
tapping and poking them on this side and that with a stick to check
and curb them. Why is that? Because he sees that he could be flogged,
imprisoned, fined or blamed if he let them stray into the crops. So
too I saw in unwholesome states danger, degradation and defilement...
Two Kinds of Thought
If you use the wise reflection method, it is important to focus on the anger rather than on 'yourself'. You must think: "This anger is harmful" (rather than "I am harmful").
The Buddha did not teach the 'self' or 'I' is the ultimate cause of problems & suffering. The Buddha taught 'ignorance' or 'not-knowing' is the ultimate cause of problems.
Therefore, we think/reflect: "Anger is bad & harmful" (and not "I am bad & harmful").
