We said in the beginning of this description that the vital body is an exact counterpart of the dense body with one exception: it is of the opposite sex or perhaps we should rather say polarity. As the vital body nourishes the dense vehicle, we may readily understand that blood is its highest visible expression, and also that a positively polarized vital body would generate more blood than a negative one. Woman who is physically negative has a positive vital body, hence she generates a surplus of blood which is relieved by the periodical flow. She is also more prone to tears, which are white bleeding, than man, whose negative vital body does not generate more blood than he can comfortably take care of. Therefore it is not necessary for him to have the outlets which relieve excess of blood in woman. _The Desire Body._ In addition to the visible body and the vital body we also have a body made of desire stuff from which we form our feelings and emotions. This vehicle also impels us to seek sense gratification. But while the two instruments of which we have already spoken, are well organized, the desire body appears to spiritual sight as an ovoid cloud extending from sixteen to twenty inches beyond the physical body. It is above the head and below the feet so that our dense body sits in the center of this egg-shaped cloud as the yolk is in the center of an egg. The reason for the rudimentary state of this vehicle is, that it has been added to the human constitution more recently than the bodies previously mentioned. Evolution of form may be likened to the manner in which the juices in the snail first condense into flesh and later become a hard shell. When our present visible body first germinated in the spirit, it was a thought-form, but gradually it has become denser and more concrete until it is now a chemical crystallization. The vital body was next emanated by the spirit as a thought-form and is in the third stage of concretion which is etheric. The desire body is a still later acquisition. That also was a thought form at its inception, but has now condensed to desire stuff, and the mind, which we have only recently received, is still but a mere cloudy thought form. Arms and limbs, ears and eyes are not necessary to use the desire body, for it can glide through space more swiftly than wind without such means of locomotion as we require in this visible world.
