Premanand Maharaj Ji
Why do I get angry even when I know it is wrong, and then regret it?
Chant a great deal; a cool heart is slow to anger
We get angry when we see the other person as separate and in the wrong, not as Bhagwan within. Plenty of Naam jap cools the heart, and a cool heart does not quickly get angry.
Naam jap cools the heart, and anger does not come quickly in a cool heart.
