Day by day, issue by issue, the greatest internal obstacles i observe, are cognitive dissonance, and emotional dissonance, where people resist change itself, known to produce emotional depression, even when change is allowed. We could say this is resistance to what 'is', preferring attachment to an illusion. The depth of attachment is often associated with the level of 'investment' in a paradigm. Being willing to let go of all that has passed, to sustain a position of neutrality in accepting the flow of the moment in the now, is the only sustainable position to stay in the flow of truth and reality.
