According to the mystical idea there are four principal elements which can be distinguished and one which is indistinct. The distinct elements are earth, water, fire, and air. They are not elements in the sense in which a scientist would use this word, but according to the meaning that the mystic attaches to it. The indistinct element is the ether. All these elements are in the body of man, in his mind, and in his deeper self. The whole edifice of an individual existence is built by means of these five distinct elements, and it is not necessary for a certain element which is predominant in one plane of existence, to continue to be so on all other planes. It is possible for there to be harmony between the elements which are predominant on the inner plane and those which are predominant on the outer plane. In short, it is according to the working of the different elements in one's being that one is responsive to the different colors which represent the different elements.
