There are two kinds of bodies for every individual soul — a gross body made of five gross elements and a subtle body made of three subtle elements. Within these bodies, however, is the spirit soul. One must find the soul by analysis, saying, “This is not it. This is not it.” Thus one must separate spirit from matter.
