VI. Thought-forms and the Human Aura

These three kinds of colours are not ranged as it were alongside each other in the human aura; they are not each enclosed in a separate section of space, but they interpenetrate each other in the most varied ways. All three kinds can be seen playing through each other in one region of the aura, just as a physical body such as a bell can be heard and seen simultaneously. The aura thereby becomes an exceedingly complicated phenomenon: for we have as it were to do with three auras within each other and interpenetrating each other. The difficulty can be overcome however by directing attention to the three kinds alternately. We then do in the super-sensible world something similar to what we do in the sensible, for example, when we close our eyes in order to give ourselves up fully to the impression of a piece of music. The “seer” has as it were three different organs for the three kinds of colours. And in order to observe undisturbed, he can open or close any one of the organs to impressions. As a rule only the one kind of organ can at first be developed by a “seer,” namely, that for the first kind of colours. A person at this stage can see only the one aura; the other two remain invisible to him. In the same way a person may be accessible to impressions from the first two but not from the third. The higher stage of the “gift of seeing” consists in a person's being able to see all three auras and for the purpose of study to direct his attention to the one or the other.
