In Judaism Shin also stands for S-letter symbolism for the word "Shaddai," a name for God.

In Jewish tradition the letter Shin is inscribed on the Mezuzah, a vessel which houses a scroll of parchment with Biblical text written on it. . Sometimes the whole word "Shaddai" is written.

The upper signs in the circle are astrological symbols of Leo and Virgo.

The other kabbalistic sign oposit of "Shin" could be a "Caput Draconis", which is the “Dragon’s head” or North Lunar Node in astrology. I am not 100% sure of this one, though.

Thanks!
