As far as I can see, no direct intellectual contact is possible, except under certain circumstances. There is, of course, a great deal of thought-vibration taking place in the world, to which the best analogy is wireless telegraphy. There exists an all-pervading emotional medium, into which every thought that is tinged with emotion sends a ripple. Thoughts which are concerned with personal emotion send the firmest ripple into this medium, and all other thoughts and passions affect it, not in proportion to the intensity of the thought, but to the nature of the thought. The scale is perfectly determined and quite unalterable; thus a thought, however strong and intense, which is concerned with wealth or with personal ambition sends a very little ripple into the medium, while a thought of affection is very noticeable indeed, and more noticeable in proportion as it is purer and less concerned with any kind of bodily passion. Thus, strange to say, the thought of a father for a child is a stronger thought than that of a lover for his beloved. I do not know the exact scale of force, which is as exact as that of chemical values--and of course such emotions are apt to be complex and intricate; but the purer and simpler the thought is, the greater is its force. Perhaps the prayers that one prays for those whom one loves send the strongest ripple of all. If it happens that two of these ripples of personal emotion are closely similar, a reflex action takes place; and thus is explained the phenomenon which often takes place, the sudden sense of a friend's personality, if that friend, in absence, writes one a letter, or bends his mind intently upon one. It also explains the way in which some national or cosmic emotion suddenly gains simultaneous force, and vibrates in thousands of minds at the same time. The body, by its joys and sufferings alike, offers a great obstruction to these emotional waves. In the land of spirits, as I have indicated, an intention of congenial wills gives an instantaneous perception; but this seems impossible between an embodied spirit and a disembodied spirit. The only communication which seems possible is that of a vague emotion; and it seems quite impossible for any sort of intellectual idea to be directly communicated by a disembodied spirit to an embodied spirit. On the other hand, the intellectual processes of an embodied spirit are to a certain extent perceptible by a disembodied spirit; but there is a condition to this, and that is that some emotional sympathy must have existed between the two on earth. If there is no such sympathy, then the body is an absolute bar. I could look into the mind of Amroth and see his thought take shape, as I could look into a stream, and see a fish dart from a covert of weed. But with those still in the body it is different. And I will therefore proceed to describe a single experience which will illustrate my point.
