In this diagram the inner circle shows the polarity of the Houses, whether positive or negative, the next circle outward shows the polarity of the Hours, and the outside circle shows that of the Quadrants, which is summative of the Houses and Hours. Applying this to the subject of planetary action, it will be seen that a planet occupying the S.E. quadrant of the heavens will exert a positive influence, but that its influence will be largely negatived when it occupies the second half of the 11th House in the course of its rising, and similarly, that a planet in the S.W. quadrant will exercise a negative influence, which will be rendered more positive when the planet comes to the first half of the 8th House in the course of its setting. The fact that male horoscopes are generated from the S.E. and N.W. quadrants and female from the S.W. and N.E., goes to show that these ascriptions are valid, and when we further consider that human vitality is lowest at the two points that are occupied by the negative influence, and highest at those that are here shown to be positive, should, in my opinion, go a long way towards establishing this order in our astrological scheme of things. Now, if we consider the whole earth to be surrounded with etheric vibrations and interpenetrated by them, we may also legitimately refer these vibrations to colours and sounds since all the forces of Nature are interchangeable and convertible. Such a conception lends itself at once to experimental proof, and, as the result of researches carried on during successive years by Carl von Reichenbach, we have a definite scheme of colour attributable to the different sections of the heavens. It is shown that there is a form of electricity visible to persons of a highly sensitive nature when placed in the dark. In _The Sensitive Man_ Reichenbach has given a mass of experiments which show that the Od fluid undergoes a variety of changes according to the magnetic relations of the subject or object from which they proceed. In the second volume there is a description of the Earth-Aura. This is not, as one might suppose, a composite of the various auras of its geological constituents, but a thing apart and independent of human, animal, vegetable and other emanations. Every body has its own aura, and these blend upon contact or within auric distance, producing changes in the magnetic relations of the bodies concerned. The human aura is like that of the crystal and has an obvious polarity. Thus the auric colour at the head is blue while that at the feet is dark red; the right side is grey-blue and the left side yellow. Now this answers exactly to the polarity of the visible heavens, for it is observed that Blue, the most magnetic colour, is associated with the North or midnight point; Red, the most electric, with the South and mid-day; the neutral to the East and the dawn; and the Yellow to the West and sunset.
