I see an ocean inside M.
The sea seems to be always the same, in the same place, but transformations, actions and internal processes run there all the time. Loyal to itself, and also loyal to nature’s continuous flow/change/movement.
It seems to be blue or green etc., but we know it’s because it absorbs light and reflects the colour of the sky. It reflects something that is above it.
Many of the lines I highlighted contributed to my eyes-being-wet condition. To me, M is experiencing something very fulfilling. And I don’t mean just what he also clearly says.
