Here's the problem: Wandering minds wander towards unhappiness (or away from happiness?) but also, simultaneously, towards inspiration. You may stumble across one on the way towards the other, or carry one on your back as you trek in the direction of its opposite, but within the realm of psychological states their territory is adjacent. This is why so many people have pointed out the correlation between creativity and depression. It's not a question of causation but of limitation: Given a finite number of mental/emotional moods on the road to somewhere else, we are bound to meet (come into the company of) either the High or the Low. This present moment is the Middle. One step in either direction invites the flip of a coin.
The issue is that we believe a coin has two sides, and must always proclaim Heads or Tails. We forget that a physical coin---with its shape, mass, and form in three dimensions---bursts beyond the abstraction of probability. We forget about that bit in the middle. That numinous realm, within the spin of which we fervidly circle, is where we spend most of our time, until, under the impression that it all can only ever be One or The Other, we throw all our weight against an arbitrary side, hoping to topple it and yield the definitive. But certainty can never be achieved, only imagined. Finality is a mirage. If a coin holds within it (is charged with) a perfect 50-50 probability, then any one coin toss means nothing. We will always have both Heads and Tails. Flipping Heads and then stopping does not eliminate the future yielding of Tails.
In other words, whether standstill or wandering, we are only tossing coins.
But I'm already contradicting myself, because I was trying to say that Duality was an Illusion.
I'm wandering again.
