If you have a strong ego [and] something good happens to an acquaintance of yours, [it] makes you feel bad. It's called envy. ... The ego thinks something has been taken away from you because somebody else has received something good. It's a complete illusion, but that's the madness of the ego.
Eckhart TolleYou may not yet be able to bring your unconscious mind activity into awareness as thoughts, but it will always be reflected in the body as an emotion, and of this you can become aware.
Eckhart TolleOn a deeper level you are already complete. When you realize that, there is a joyous energy behind what you do.
Eckhart TolleThere is nothing that strengthens the ego more than being right. Being right is identification with a mental position - a perspective, an opinion, a judgement, a story. For you to be right, of course, you need someone else to be wrong, as so the ego loves to make wrong in order to be right.
Eckhart Tolle
