When viewed by spiritual sight, it appears that there are in this desire body a number of whirling vortices. We have already explained that it is a characteristic of desire stuff to be in constant motion, and from the main vortex in the region of the liver there is a constant outwelling flow which radiates towards the periphery of this egg-shaped body and returns to the center through a number of other vortices. The desire body exhibits all the colors and shades which we know and a vast number of others which are indescribable in earthly language. Those colors vary in every person according to his characteristics and temperament and they also vary from moment to moment as passing moods, fancies or emotions are experienced by him. There is however in each one a certain basic color dependent upon the ruling star at the moment of his birth. The man in whose horoscope Mars is peculiarly strong usually has a crimson tint in his aura, where Jupiter is the strongest planet the prevailing tint seems to be a bluish tone, and so on with the other planets. There was a time in the earth’s past history when incrustation was not yet complete, and human beings of that time lived upon islands here and there, amid boiling seas. They had not yet evolved eyes or ears, but a little organ: the pineal gland, which anatomists have called _the third eye_, protruded through the back of the head and was a _localised organ of feeling_, which warned the man when he came too near a volcanic crater and thus enabled him to escape destruction. Since then the cerebral hemispheres have covered the pineal gland, and instead of a single organ of feeling, the whole body inside and out is sensitive to impacts, which of course is a much higher state of development. In the desire body every particle is sensitive to vibrations similar to those which we call sight, sounds and feelings and every particle is in incessant motion rapidly swirling about so that in the same instant it may be at the top and bottom of the desire body and impart at all points to all the other particles a sensation of that which it has experienced thus every particle of desire stuff in this vehicle of ours will instantly feel any sensation experienced by any single particle. Therefore the desire body is of an exceedingly sensitive nature, capable of most intense feelings and emotions. _The Mind._
