Uncertainty is the bridge to certainty.
Most people want to get to certainty by controlling their experience by any means possible in the form of mind-based distractions. However, this thought-based form of control by doing will never allow you to access the pure potential of who you really are, which is completely fulfilled at all times.
To really allow unlimited access to the certainty of anything, one must practice the feeling of certainty. Not in a fake-it-till-you-make-it way, because that would be inauthentic - but in a real-time allowing-and-embracing-of-all-that-is way.
It's when we can let go of a desired outcome or goal that we allow our innate intelligence and wisdom to shine and guide the way to certainty.
