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 TolleMany things in your life matter, but only one thing matters absolutely.It matters whether you succeed or fail in the eyes of the world. It matters whether you are healthy or not healthy, whether you are educated or not educated. It matter whether you are rich or poor - it certainly makes a difference in your life. Yes, all these things matter, relatively speaking, but they don't matter absolutely.There is something that matters more than any of those things and that is finding the essence of who you are beyond that short-lived entity, that short-lived personalized sense of self.
Eckhart TolleA self - a me - exists in every thought and every emotion. Suffering arises through complete identification with thinking and emotions.
