I treat my ego like it is water. I can make it solid, liquid, or let it vanish. If someone flips me the bird, I make the ego into vapor. If my plans are interrupted by an accident, I make the ego liquid. If someone threatens my life, I make the ego solid like ice. When the ego is not needed, it joins the waters of the world.
Anger is just frustration that tells me I not using the ego tool correctly.
The ego is the most useful illusion the Dao has ever conjured up.
