Premanand Maharaj Ji
How can I stop getting angry at small things?
Remember God in the other person
Anger brings violence and insult to those who deserve respect, and no one has ever gained from anger, only from forgiveness. Keep the Name and form of God in memory, or see the person who provokes you as your Beloved.
No one has ever gained anything from anger. Whenever anyone has gained, it came from forgiveness, not from anger.
