Fear seems to have many causes. Fear of loss, fear of failure, fear of being hurt, and so on, but ultimately all fear is the ego's fear of death, of annihilation. To the ego, death is always just around the corner. In this mind-identified state, fear of death affects every aspect of your life.
Eckhart TolleWhen you are suffering, when you are unhappy, stay totally with what is Now. Unhappiness or problems cannot survive in the Now.
Eckhart TolleMany people in this world are still so identified with every thought that arises in their head. There is not the slightest space of awareness there.
Eckhart TolleWhereas the notion of purpose before was always associated with future, there is now a deeper purpose that can only be found in the present, through denial of time.
