When we come to consider the additional facilities which it offers in the observation of animate objects we see still more clearly the advantages of the astral vision. It exhibits to the clairvoyant the aura of plants and animals, and thus in the case of the latter their desires and emotions, and whatever thoughts they may have, are all plainly shown before his eyes. But it is in dealing with human beings that he will most appreciate the value of this faculty, for he will often be able to help them far more effectually when he guides himself by the information which it gives him. He will be able to see the aura as far up as the astral body, and though that leaves all the higher part of a man still hidden from his gaze, he will nevertheless find it possible by careful observation to learn a good deal about the higher part from what is within his reach. His capacity of examining the etheric double will give him considerable advantage in locating and classifying any defects or diseases of the nervous system, while from the appearance of the astral body he will be at once aware of all the emotions, passions, desires and tendencies of the man before him, and even of very many of his thoughts also. As he looks at a person he will see him surrounded by the luminous mist of the astral aura, flashing with all sorts of brilliant colours, and constantly changing in hue and brilliancy with every variation of the person's thoughts and feelings. He will see this aura flooded with the beautiful rose-colour of pure affection, the rich blue of devotional feeling, the hard, dull brown of selfishness, the deep scarlet of anger, the horrible lurid red of sensuality, the livid grey of fear, the black clouds of hatred and malice, or any of the other hundredfold indications so easily to be read in it by a practised eye; and thus it will be impossible for any persons to conceal from him the real state of their feelings on any subject. These varied indications of the aura are of themselves a study of very deep interest, but I have no space to deal with them in detail here. A much fuller account of them, together with a large number of coloured illustrations, will be found in my work on the subject _Man Visible and Invisible_. Not only does the astral aura show him the temporary result of the emotion passing through it at the moment, but it also gives him, by the arrangement and proportion of its colours when in a condition of comparative rest, a clue to the general disposition and character of its owner. For the astral body is the expression of as much of the man as can be manifested on that plane, so that from what is seen in it much more which belongs to higher planes may be inferred with considerable certainty.
