The rock to show the nerve
The oblique line on the rock show the sun has vessels.
The long and short of it, it was made to show the sun is alive and has subconsciousness."
(When I saw the rock of Miyagi Prefecture, Japan which has the lines in it previously, the subconsciousness of it told me Stone god put the lines so that they could show they had the vessels or nerves and were alive.)
