Life's Barriers
Life can throw up so many barriers all at once! When this happens, one needs to crawl over, under, around, or through them. There is simply no other way around barriers.
In another vein, a DNA helix is a barrier that keeps intelligence barricaded into physical form. Likewise, the barrier of your body prevents you from floating away into the ether where you might well dissociate into the constituent archetypes, neuroses, and disunified Awareness from which your personality is constructed.
