As there is a category of facts to which our senses are our best available but very imperfect guide, as there is a category of truths which we seek by the keen but still imperfect light of our reason, so according to the mystic, there is a category of more subtle truths which surpass the reach both of the senses and the reason but can be ascertained by an inner direct knowledge and direct experience. These truths are supersensuous but not the less real for that — they have immense results upon the consciousness changing its substance and movement, bringing especially deep peace and abiding joy, a great light of vision and knowledge, a possibility of the overcoming of the lower animal nature, vistas of a spiritual self-development which without them do not exist.
A new outlook on things arises which brings with it, if fully pursued into its consequences, a great liberation, inner harmony, unification — many other possibilities besides. These things have been experienced, it is true, by a small minority of the human race, but still there has been a host of independent witnesses to them in all times, climes and conditions and numbered among them are some of the greatest intelligences of the past, some of the world’s most remarkable figures.
Must these possibilities be immediately condemned as chimaeras because they are not only beyond the average man in the street but also not easily seizable even by many cultivated intellects or because their method is more difficult than that of the ordinary sense or reason? If there is any truth in them, is not this possibility opened by them worth pursuing as opening a highest range to self-discovery and world-discovery by the human soul? At its best, taken as true, it must be that — at its lowest, taken as only a possibility, as all things attained by man have been only a possibility in their earlier stages, it is a great and may well be a most fruitful adventure.
