If, as there is every reason to believe, clairvoyance depends on the unfolding of the spirit’s perception, then the extent of that unfolding marks the degree of its perfection. However great or small this may be, the state itself is the same, differing only in degree, whether observed in the Pythian or Delphic oracle, the visions of St. John, the trance of Mohammed, the epidemic catalepsy of religious revivals, or the illumination of Swedenborg. The revelations made have a general resemblance, but they are so colored by surrounding circumstances that they are extremely fallible. The tendency of the trance is to make objective the subjective ideas acquired by education. This is exhibited in cases of religious ecstasy and trance, when the subject sees visions of winged angels and of Christ; transforming dogmas and beliefs into objective realities. Such revelations, of course, have no more value than the illusory visions of the fever-stricken patient. Yet there is a profound state which sets this aside, and divests the mind of all trammels, and brings it into direct contact with the thought atmosphere of the world--the psycho-ether. Time and space for it, then, have no existence, and matter is transparent. The weakening of the physical powers by disease is favorable to sensitiveness. As the senses are deadened, the powers of the interior consciousness are quickened, and a new world rises above the horizon of the corporeal senses. Evidence of the truth of clairvoyance was given in the _Brooklyn Eagle_, soon after the loss of the “Arctic,” in 1854. The wife, son and daughter of Captain Collins were making the tour of Europe, and the Captain, to gratify a passing whim, consulted a clairvoyant as to their locality. The answer was that they were at that time visiting a church, which was accurately described. When the wife’s letter came, it contained a narrative of a visit to a church at exactly the same hour, describing it as the clairvoyant had done, thus showing that the communication was quite correct. As the family had arranged to return on the “Arctic,” and as the ship was a day late, of course Captain Collins became anxious. Sunday and Monday passed without news from the ship, and his anxiety increased. He thought of the clairvoyant and called on her. At first, although apparently deeply entranced, she could see nothing. Everything was in a cloud. At length she was able to see the three persons standing on the deck of a ship, amid great confusion, and almost concealed in fog and mist. This was all she could discern. This was nearly two days before the telegraph announced the loss of the “Arctic,” and the arrival of a boat-load of survivors on the Canadian coast. But the Collins family were not among the saved.
