It seems like such an easy concept--knowing where you are now. But if you think about it, it makes all the difference in the world. You don't have to worry about where you're going; you don't even have to know what you're doing. As long as you're in the moment, as long as you know (literally) where you are in space, how it feels to breathe there, how your feet feel in their shoes on this floor, knowing what your eyes see and your ears hear, then you'll be fine. The information you need will always come to you, a solution of some sort will always arrive, if you are present.
But that's a big 'if.' We're so rarely present; our brains love to whip us around, whip us into a frenzy of anticipation, anxiety, what if's, and random worries. But if we can BE present, we could realize we have all the answers, or the ability to learn the skills to find the answers, at our fingertips.
We know this because it's true. We've had moments of absolute clarity, moments of absolute presence, and I'll bet you that they happened simultaneously, every time.
