When we angry we give the other person, institution or circumstance total control over ourselves. Anger is usually a sign that something is broken and needs fixing. This not to be confused with "righteous" anger like anger over social injustice, the holocaust, etc.

Anger and it's close cousin, resentment, are the basis of all forms of spiritual disease.

I could have been angry with the doctors who missed the Dx but after all it wasn't them that gave me cancer. I also could have not put off the referal with the ENT as long as I did.

(Doctor) Paul O. once said that " Nothing, absolutely nothing, happens by mistake in God's world."
