“ But we find ourselves in possession of a consciousness which is capable of appreciating only three of those dimensions, and only matter of certain degrees of tenuity. All matter of other and higher degrees is for us as if it did not exist. All dimensions beyond the three are also to us as though they did not exist. ”

“ We should say, then, not that the possession of astral vision at once causes the man to appreciate the fourth dimension, but rather that it gives him the power to develop that faculty by long, careful and patient practice, if he knows anything about the matter and cares to take the trouble. Entities belonging to the astral plane, and presumably ignorant of any other (such as nature-spirits, for example) have by nature the faculty of seeing the fourth-dimensional aspect of all objects. ”

“ In physical life we can normally conceive only three, though by careful special training the brain may be educated into grasping some of the simpler fourth-dimensional forms. The astral consciousness has the power of grasping four of these dimensions, but it by no means follows that a man who opens his astral consciousness immediately perceives the extension of every object in four dimensions; on the contrary, it is quite certain that the average man does not perceive this at all when he enters the astral plane. ”
