The whole movement of happiness, unhappiness, happiness, unhappiness, could be called unhappiness. You're suffering because your state of mind is in flux, moving back and forth. The ego's happiness is really a form of suffering, because it cannot live without unhappiness.
Eckhart TolleThe next step in human evolution is to transcend thought. This is now our urgent task. It doesn't mean not to think anymore, but simply not to be completely identified with thought, possessed by thought.
Eckhart TolleYou cannot fight against the ego and win, just as you cannot fight against darkness. The light of consciousness is all that is necessary. You are that light.
Eckhart Tolle
