“Anger is like a hot coal. It burns the person holding on to it,” observed Buddha.
And it also burns the person who did not ignite it, because the person holding on to it has decided to not let it go.
Sometimes when we are angry with someone, we inflict that on everyone else. Sometimes then when we are not angry with anyone, that anger becomes our default setting.
This makes us inflict anger on everyone, regardless of what they did or did not do.
Your relationships and your mood are not that cheap, are they?
