I was wondering what the magic manuals were that "Jean" was talking about. This is the closest I could find. It is an excerpt from Lauron William de Laurence, The Great Book of Magical Art, Hindu Magic and East Indian Occultism
, 12th edition, Chicago, 1914. This passage is about how eye-gazing can be used to psychologically overpower people.
L. W. de Laurence
The Art of Fascination. I call fascination a binding, because it is effected by a look, glance, or observation, in which we take possession of the spirit, and overpower the same, of those we mean to fascinate or suspend; for it comes through the eyes, and the instrument by which we fascinate or bind is a certain, pure, lucid, subtil, generated out of the ferment of the purer blood by the heat of the heart, and the firm, determined, and ardent will of the soul which directs it to the object previously disposed to be fascinated. This doth always send forth by the eyes, rays or beams, carrying with them a pure subtile spirit or vapour into the eye or blood of him or her that is opposite. So the eye, being opened and intent upon any one with a strong imagination, doth dart its beams, which are the vehicle of the spirit, into whatever we will affect or bind, which spirit striking the eye of them who are fascinated, being stirred up in the heart and soul of him that sends them forth, and possessing the breast of them who are struck, wounds their hearts, infects their spirits, and overpowers them.
