This is not good news for a lot of people. Much work and attention go into becoming the person we think we ought to be, or want to be. When we then fulfill some image of Self that derives from our family or culture, satisfaction is far from assured and disappointment can grow as we realize that our wanting for something new, or something more, doesn't cease. More often than not, 100% fulfillment is not achievable anyway. In the end, we may feel like we've failed to live up to our own expectations (which as we eventually discover, were probably not really our own). To the extent that our "success" as a person is tied to impermanent and very imperfect conditions, self-satisfaction is elusive at best and at worst deeply fractured.
More often than not, those of us on the path of awakening eventually discover that we are not the person we thought we were. This awareness can cause discomfort, to say the least. It isn't always success or failure that triggers this realization, but something often does. It may be a situation at work, or in ones family, where identity issues are often paramount. Or it may be in a relationship, where ones identity is felt to be at stake.
The good news is that recognizing this truth gives us the space we need, the freedom to continue becoming more of who we are. Seem like a paradox? It IS, but only if you can't or won't believe that we are much greater, much bigger, much smarter, much more powerful in fact than our limited identity allows us to be. I wouldn't know how to define the limits of Self, if there were any to define. But by setting aside and thereby gaining freedom from self-imposed, socially and culturally derived images and conceptions of identity, we allow ourselves to push beyond the artificial limits of self that invariably cause suffering in our lives when these conceptions don't conform with ever changing conditions.
As the layers come off, new layers of identity invariably take their place. The action of being human, in so far as it involves awakening, seems to be an exercise in creating more and more freedom, freedom to be more and more of who we really are -- freedom to expand our container so that we are able to experience more of self and life. Growing up is another way to describe awakening. It is, it seems, a developmental process with no apparent limits, and no end.
