It is said that clairvoyance and clairaudience powers are "natural gifts," but they are really the result of an evil state, in which evil spirits are able to manifest their power and presence. Crystal gazing is also merely a means of inducing this passive state, and so with all the various methods in vogue in the East and elsewhere, to bring about the manifestations and workings of supernatural powers. The principle is the same. The key to all these, and other Satanic workings in the human frame, is the need of the suspension of the mental activity; whereas in all Divine revelations, the mental faculties and powers are unchecked, and in full operation.
The people at the foot of Mount Sinai "saw God," yet they were not "passive." Vision - whether mental or physical - is really active and not passive, that is, separated from volition and personal action; and "visions" may be either physical, mental or spiritual.
