So far for humans it has been the case that ego develops and then humans are stuck with it for the rest of their lives.
Eckhart TolleWhat you think of as they past is a memory trace, stored in the mind, of a former Now. When you remember the past, you reactivate a memory trace -- and you do so now. The future is an imagined Now, a projection of the mind. When the future comes, it comes as the Now. When you think about the future, you do it now. Past and future obviously have no reality of their own. Just as the moon has no light of its own, but can only reflect the light of the sun, so are past and future only pale reflections of the light, power, and reality of the eternal present. Their reality is "borrowed" from the Now.
Eckhart TolleInternal and external are ultimately one. When you no longer perceive the world as hostile, there is no more fear, and when there is no more fear, you think, speak and act differently. Love and compassion arise, and they affect the world.
