The Secret of Karmic Connections
Judy Hall has written a bestseller in the U.S. (a true reference work written for advanced soul magicians) on how to recognize and charge your soulmate!
Soul partnership is not described at length with pure "hoax", but as a link showing up in both partners. A connection, therefore, has not much to do with cosmic with allegedly existing vibrations, but with reason and true, unconditional love!
It is therefore an interesting and novel advance in the flooded (with pseudo-esoteric messages) book world on the "soul mate calculate" topic.
Calculating your soulmate is not a mathematical approach, however, you may find yourself comfortable with a bit of extra knowledge about numbers, numerology and general "magical terms" as they will of course be on your interesting route to calculating and ultimately finding your true soulmate!
