I noticed that symbol u posted unity/balance is the star of david. It's interesting you posted this because i was meditating on this a few days ago and I felt my energy go up from my solar plexus to my heart center.

I feel so much better like my whole life has been invigorated with positive energy. I hope that soon enough I can move forward to the next level.

Also, while meditating on that symbol it came to me that they are representations of masculine/feminine energy and when they are placed together as in the star of david it represents the unity of man and woman through sexual intercourse as in the unity of the cosmos.

It makes you think the secret of eternity lies within the unity of woman and man.
