We need a reason to live our lives - a final justification for why we do everything we do. Pleasure is not a sufficient reason, or else we would simply overdose on heroin and go out of this world with a smile.
Without a reason to live, a sense of meaninglessness haunts our steps, and we may have a suspicion that we are fooling ourselves by working so hard.
We all do in fact have reasons for living, but from time to time, as we mature, those reasons are often found to be faulty, or invalid, or simply not satisfying any more. And if we create our own reason for living, the question will haunt us, why did we create that particular meaning? Is it the right one? What makes it valid? Is it based on fantasy, or perhaps on fear? Is it worthy enough to dedicate our entire lives to?
Yet when we are still, despite whatever we believe, there is something inside that motivates us to live, and to continue to live, through the blackest night. There seems to be a meaning built into us, even when we cannot capture it in words. It is something we discover, not create - something we feel, not decide. And when we hear the words of the deep thinkers, something often resonates, letting us know we are not alone in our questing, and that the illusive reason we seek is not unique to us. If our eyes and ears are open, we discover the commonality between us and others in attempting to name the unnameable.
