The soul comes from the Latin "anima."

The soul corresponds to a vital principle that literally "animates" the body. The animal, human, or plant kingdoms are deemed to have a soul, to move, and to be receptors and emitters of these invisible flows called "emotions."

This vital impetus, which we symbolize by an upward-pointing triangle, constitutes an aspiration that starts from the manifested world, the here-below, to strive upward.
