when i was a kid i used to draw a lots of circles and spirals. as of now i know that they mean circulation and vortex.
the people on the photos are actually dead. but i believe that only our physical human body dies and our soul goes on another journey in a new body.
the spiral symbol means vortex. if it aims right it means creative forces. if it aims left it means destructive forces. the evolution of the soul passes in a spiral line: moves in circles but always go up one level.
