The Preciousness of Uncertainty and Doubt

There is a great gift provided to us directly from Life itself.  It a gift that I am calling the Preciousness of Uncertainty and Doubt.   This the basic law that Life enforces to bring us to a full and authentic awakening to the Self.  The good news is that it works, the bad news is that the vehicle that Life uses can also be the catalyst to deep resistance and suffering. 
The good news...
The good news is that Life is unrelenting in its movement to awaken all to the basic Reality.  Life provides us with exactly the appropriate teacher and teaching at the perfectly appropriate time.  This is evidenced by the appearance of uncertainty and doubt in our lives.  Essentially, self-doubt exists because as long as we have some notion or idea of ourselves as fixed, Life will disrupt that pattern with great doubt.
When we become very certain (of ourselves, our ideas, our beliefs, etc.) Life has already provided the necessary medicine- uncertainty.
There really is no such thing in the quest for spiritual awakening as self-confidence, self-worth, nor is there any certainty to be found.  Psychology and belief systems may provides temporary (and sometimes useful) senses of self-worth and certainty, but when it comes to Reality there's really no such thing.  The sooner we get clear on that and give up the insistence on finding some certainty or developing self-worth, the sooner we come into accord with the nature of Life.
The bad news...
The bad news isn't really bad news, it just implies that likely Life is going to have to be very fierce in tearing away the illusions that we hold to so strongly.  Ultimately, any certainty or self-worth that we discover only sets up the conditions for our disappointment, because NO idea, belief, feeling, or experience is lasting...and the only 'things' we can rely on are those things.  In this way, Life is inviting us to give up our need for certainty or a good feeling about ourselves, and arrive right Here, where we rely on Nothing.
The funny thing is that in relying on Nothing, we simultaneously rely on Everything...so the need, desire, or drive for certainty is just irrelevant.  It's not that we've arrived at certainty and 'found our self', it's simply a matter of no longer wanting for anything at all.
