Satipatthana Sutta: Third Foundation, Division Through Doubt from Seattle Insight Meditation on Vimeo.
The mind finds endless reasons to energetically split itself in two. "Shoulds," denials, rationalizations, resentments, and countless other states are energetic divisions, where the mind is trying to have what it wants while hiding from its assumed reality. Doubt is perhaps the most common expression of this pattern. Doubt reaches for what it wants with half a heart because it fears the repercussions of being a failure.
