The shore, the beach - lands end, waters end. A place of endings and beginnings. The point where change is constant - the sand and rocks constantly rearranged, tides rise and fall. Marks made, erased. A place of redemption - decisions made, regrets perhaps, eventually washed clean by the incessant tides.
Interestingly, I now live very far from any ocean and yet I feel it's transformative and primal power as I reflect on where I stand now. While the constant flux of water meeting land is not part of my world now, I sometimes fell I live at the meeting point of two similarly large and different entities - the vast Great Plains and the Rocky Mountains. I live where these two opposites meet - not unlike where the water of the sea meets the land.
