At first it is not easy for people to believe that feelings like reverence, respect, and so forth, have anything to do with their perceptions. This comes from the fact that one is inclined to think of perception as a faculty quite by itself, one that stands in no relation to what otherwise happens in the soul. In so thinking, we do not remember that it is the soul which perceives. And feelings are for the soul what food is for the body. If we give the body stones in place of bread its activity will cease. It is the same with the soul. Veneration, homage, devotion, are as nutriment which makes it healthy and strong, and especially strong for the activity of perception. Disrespect, antipathy, and under-estimation, bring about the starvation and withering of this activity. For the occultist this fact is visible in the aura. A soul which harbours the feelings of devotion and reverence, brings about a change in its aura. Certain yellowish-red or brown-red tints will vanish, and tints of bluish-red will replace them. And then the organ of perception opens. It receives information of facts in its neighbourhood of which hitherto it had no knowledge. Reverence awakens a sympathetic power in the soul, and through this we attract similar qualities in the beings which surround us, which would otherwise remain hidden.
