Ego is in everyone. Ego is the same energy which on one hand is very important for our physical life and on other hand it is the same energy which burns us in worldly fire.
Understanding ego is transforming it.
Ego gets activated Immediately If the person in front of us is throwing ego tantrums. Seing him we will have a ego hangover.
We become same like that person , If the other is pulling us down to get superiour feeling or to show that we are wrong and he is better than us. This is enough to activate ego in us.
If in case at that time we are able to keep our ego calm and see this ego dance and shift in self love from ego zone , then it is a super grace of God on us and lot of happiness, peace and bliss is going to shower on us.
Second, Now we can think that God has opened the doors of the kingdom of love, peace and bliss as now he has taught us how to deal with this high worldly gravitational force being in the body.
This is just being witness to all.
Ashtavakra Geeta is all about just being witness.
