What is the individual Human Spirit or Soul?

Domiunus Vobiscum (Lord be with you) Et cum Spiritu tuo (and with your spirit).. The individual is composed of two facets... (1) the earthly you in substance.....represented in symbolic languane as an equal sided square..... and (2) the spiritual you.... represented by a circle. You may note here that the square and circle are represented by an interlacing of a compass and carpenter's square in the emblem of the freemasons. The representation is to "Square the Circle." meaning to bring into harmony the two aspects of the self. The earthly you is mortal. The spiritual you is eternal. The spiritual you esists within you as well at Home simultaneously..... sharing as one with all souls.
