Premanand Maharaj Ji
How do I stay calm when someone insults me and hurts my ego?
See the person as only an instrument
When someone hurts you, see that he is only an instrument and God is striking at your ego. Turn to God at once and ask Him to protect you.
At that time you must see God's arrangement: this poor person is only an instrument. God, sitting in his mind, hurt my ego. Immediately start thinking of God: 'O God, hold me.'
