The human aura or atmosphere consists of a number of layers or strata one beyond the other extending out into space. By means of Dr. Kilner’s chemical screens three of these divisions may be clearly perceived.
First, what is called the “etheric double”. This is seen like a dark line, slightly greyish in colour, which extends over the whole surface of the body conforming exactly to its shape. Doubtless this is one manifestation of the double or etheric body.
Beyond this extends the “inner aura”, which is usually two or three inches broad. It conforms to the contour of the body throughout and is more or less coloured by the health of the individual and by the mental or emotional states, which may be present at that time.
Beyond this again is the “outer aura”, beginning where the inner aura ceases, and extending from three to six inches, as a rule, before it becomes invisible. It extends slightly further in the case of women than it does in men.
This aura is very variable, and is greatly influenced by all the mental and psychic conditions of the person to whom it belongs.
Its colours vary also very greatly, but this cannot as a rule be seen through the screens because they themselves are either dark red or blue. It takes a trained clairvoyant to see all the subtle gradations and variations of colour in the aura.
The best way to train yourself to see auras of this character is, perhaps, the following:
1. In a darkened room study the aspect of a good horseshoe magnet, either suspended in the air by a silk thread or placed on a support, with poles up, and vary the position of the observation until a faint luminosity is observed at the poles and along the edges of the magnet.
2. In the light repeat the same process, trying to make out these lines and the extensions and limitations of the aura.
It must be understood that this vision can be obtained artificially only through the action of the will, and by a proper focusing of the eyes, the perception of auras requiring a very different focus from ordinary sight, and this focusing is very often different in each of the two eyes.
The attempted focusing of the sight must be made with each eye separately and then with both combined. It may happen that one eye only can be focused for this special vision, or when both are found available, if both focuses are not identical, the active use of both eyes at one time may destroy the psychic sight of the sensitive eye.
It is important to master the faculty of seeing the magnetic aura in the daylight, because more complete details can thus be eventually obtained than in the dark, and this is the only way to learn how to perceive the human aura.
For the purpose of trying one’s vision in broad daylight, take a good horseshoe magnet and hold it perpendicularly in front of you, either against the background of an open outside light, such as can be obtained from looking out from the inside of a room through an open window, or against a near inside background, for instance a white or dark wall, according to the nature of the light.
Then look at the edge of the magnet with one eye only and gradually approach it or slide it away from you, until you obtain the best focus of vision.
Look steadily along the same point until it dawns on you that a kind of a quivering, narrow band of mist or vapour is flowing from the metal and prevents your sight from freely perceiving the object back of it, producing, in fact, a sort of bending of your visual rays.
As soon as you realize the presence on the edge of the magnet, of this current of vaporous mist, which may be compared to the appearance of the heated air which arises in summertime from hot fields, the first psychic visual victory has been obtained, and the perception of the other phenomena connected with the aura will only need time, perseverance and practice and, once the magnet is conquered, one may expect to speedily obtain the sight of the beautiful and intricate currents on the human body.
