We humans often forget and deny that we live on a water planet.
We live on an ocean planet and our human body consists mostly of water. So too, the collective unconscious of our psyche has been described as an ocean. The Dolphin shares both the air-breathing conscious world and the undersea unconscious world; we may liken the Dolphin to a bridge between both realms. Indeed, at one time the ancestors of the current Dolphin lived on land and then slowly returned to the sea. The Dolphin will dive deep into the ocean to explore and be nourished, as do we when we return to the unconscious sea of our dreams. We therefore see the Dolphin and its ocean as a metaphor to our diving down into the depths of the collective unconscious.
Dolphins exist in all the oceans of our planet. We humans also came from the sea eons ago. The shore is now the boundary between us. But perhaps there is a bridge; a bridge which lies in the unconscious. Is there perhaps a transcendent function; a wisdom which transcends the consciousness of both human and dolphin?
