Symbol is something that pointing from space time things or any thing to transcendent.
Symbols work as automatic button that releases energy and chanels it.

Symbol builts into psyche.
How it built in psyche.No one know,it comes from where.

Let see eg.
if Hawk fly over chicks,that have just been hatched from egg,and have never seen a hawk before.

Chicks fear from hawk.
but if a pigeon flies over,they don’t.

If the same hawk emage drawn by wood.
Chicks response are same.

in psychology this mechanism is called IRM(inner release machenism).

Means something that spontenious hit the psyche,through nervous system.
I mean it doesn’t like something you see then you think about that through thinking,feeling,sensing etc,but spontaneous response.

For the symbol of mythology are not manufactured,they can’t be ordered,invented,or permanently suppreed.They are spontaneous production of psyche.

The same principal use in symbols of mythology.
