Premanand Maharaj Ji
What should I do in the very moment anger comes?
Be silent, step away, chant Radha
Anger is a demonic tendency that destroys, so go silent, move away or chant Radha loudly. See it as Bhagwan's test and keep increasing your Naam jap.
When anger comes, become silent. When anger comes, move away. When anger comes, start loudly chanting Radha Radha.
