The pain-body wants to survive, just like every other entity in existence, and it can only survive if it gets you to unconsciously identify with it.
Eckhart TolleYou may remember the paradox of time we mentioned earlier: Whatever you do takes time, and yet it is always now. So while your inner purpose is to negate time, your outer purpose necessarily involves future and so could not exist without time. But it is always secondary. Whenever you become anxious or stressed, outer purpose has taken over, and you lost sight of your inner purpose. You have forgotten that your state of consciousness is primary, all else secondary.
Eckhart TolleI have seen cases where people seemed to become totally free of ego, and at some point in their lives the ego came back. It has happened, for example, to some spiritual teachers. At some point in their lives, they began to identify again with form.
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.
