Because of its phantom nature, and despite elaborate defense mechanisms, the ego is very vulnerable and insecure, and it sees itself as constantly under threat. This, by the way, is the case even if the ego is outwardly very confident.
Eckhart TolleOnce the pain-body has taken you over, you want more pain. You become a victim or a perpetrator. You want to inflict pain, or you want to suffer pain, or both. There isn't really much difference between the two. You are not conscious of this, of course, and will vehemently claim that you do not want pain. But look closely and you will find that your thinking and behavior are designed to keep the pain going, for yourself and others. If you were truly conscious of it, the pattern would dissolve, for to want more pain is insanity, and nobody is consciously insane.
Eckhart TolleDo not pollute your beautiful, radiant Being nor the Earth with negativity. Do not give unhappiness in any form whatsoever a dwelling place inside you.
