the result is that the molecules, having no model of leg to work on, make no physical leg whatever; and similarly in all such cases. But where we find a man who still feels the leg which the surgeon has cut off, or perceives the fingers that were amputated, then the astral member has not been interfered with, and hence the man feels as if it were still on his person. For knife or acid will not injure the astral model, but in the first stages of its growth ideas and imagination have the power of acid and sharpened steel. In the ordinary man who has not been trained in practical occultism or who has not the faculty by birth, the astral body cannot go more than a few feet from the physical one. It is a part of that physical, it sustains it and is incorporated in it just as the fibres of the mango are all through that fruit. But there are those who, by reason of practices pursued in former lives on the earth, have a power born with them of unconsciously sending out the astral body. These are mediums, some seers, and many hysterical, cataleptic, and scrofulous people. Those who have trained themselves by a long course of excessively hard discipline which reaches to the moral and mental nature and quite beyond the power of the average man of the day, can use the astral form at will, for they have gotten completely over the delusion that the physical body is a permanent part of them, and, besides, they have learned the chemical and electrical laws governing in this matter. In their case they act with knowledge and consciously; in the other cases the act is done without power to prevent it, or to bring it about at will, or to avoid the risks attendant on such use of potencies in nature of a high character.
