Ego makes you sacrifice yourself for a cause. Ego gives strength and courage and brings valor to meet challenges with endurance and perseverance. A strong ego will counteract depression. Ego is often considered selfish but it is the greatest motivating factor for creativity and generosity. Ego propels you to venture into the unknown.
There are three types of ego – sattvic, rajasic and tamasic.
Tamasic ego is barbaric, blind and self-destructive.
Rajasic ego is self-centered and causes misery to oneself and others.
Sattvic ego is creative and has protective tendencies.
If you cannot surrender, at least have a sattvic ego, as a sattvic ego is always ready to sacrifice.
