VI. Thought-forms and the Human Aura

The colour effects perceptible to the eyes of spirit which ray out round the physical man when observed in his activity, and which envelop him like a cloud (somewhat in the form of an egg) are a human aura. The size of this aura differs in different people. But an idea can be formed of it by picturing that the whole man appears on an average twice as tall and four times as broad as the physical man.
