3. That which takes a form entirely its own, expressing its inherent qualities in the matter which it draws round it. Only thought-forms of this third class can usefully be illustrated, for to represent those of the first or second class would be merely to draw portraits or landscapes. In those types we have the plastic mental or astral matter moulded in imitation of forms belonging to the physical plane; in this third group we have a glimpse of the forms natural to the astral or mental planes. Yet this very fact, which makes them so interesting, places an insuperable barrier in the way of their accurate reproduction. Thought-forms of this third class almost invariably manifest themselves upon the astral plane, as the vast majority of them are expressions of feeling as well as of thought. Those of which we here give specimens are almost wholly of that class, except that we take a few examples of the beautiful thought-forms created in definite meditation by those who, through long practice, have learnt how to think. Thought-forms directed towards individuals produce definitely marked effects, these effects being either partially reproduced in the aura of the recipient and so increasing the total result, or repelled from it. A thought of love and of desire to protect, directed strongly towards some beloved object, creates a form which goes to the person thought of, and remains in his aura as a shielding and protecting agent; it will seek all opportunities to serve, and all opportunities to defend, not by a conscious and deliberate action, but by a blind following out of the impulse impressed upon it, and it will strengthen friendly forces that impinge on the aura and weaken unfriendly ones. Thus may we create and maintain veritable guardian angels round those we love, and many a mother's prayer for a distant child thus circles round him, though she knows not the method by which her "prayer is answered."
