The sea is the vast potential of life, but it is also your dark night, which may force you to surrender some knowledge you have achieved. It helps to regularly undo the hard-won ego development, to unravel the self and culture you have woven over the years. The night sea journey taken you back to your primordial self, not the heroic self that burns out and falls to judgement, but to your original self, yourself as a sea of possibility, your greater and deeper being.
