There are certain faculties that we have that are not a part of the active thinking mind; they seem to be no part of what we might term our _conscious intelligence_. They transcend any possible activities of our regular mental processes, and they are in some ways independent of them. Through some avenue, suggestions, intuitions of truth, intuitions of occurrences of which through the thinking mind we could know nothing, are at times borne in upon us; they flash into our consciousness, as we say, quite independent of any mental action on our part, and sometimes when we are thinking of something quite foreign to that which comes to, that which "impresses" us. This seems to indicate a source of knowledge, a faculty that is distinct from, but that acts in various ways in conjunction with, the active thinking mind. It performs likewise certain very definite and distinct functions in connection with the body. It is this that is called the _subconscious mind_--by some the superconscious or the supernormal mind, by others the subliminal self. Just what the subconscious mind is no man knows. It is easier to define its functions and to describe its activities than it is to state in exact terms what it is. It is similar in this respect to the physical force--if it be a physical force--electricity. It is only of late years that we know anything of electricity at all. Today we know a great deal of its nature and the laws of its action. No man living can tell exactly what electricity is. We are nevertheless making wonderful _practical applications_ of it. We are learning more _about it_ continually. Some day we may know what it _actually is_. The fact that the subconscious mind seems to function in a realm apart from anything that has to do with our conscious mental processes, and also that it has some definite functions as both directing and building functions to perform in connection with the body, and that it is at the same time subject to suggestion and direction from the active thinking mind, would indicate that it may be the true connecting link, the medium of exchange, between the soul and the body, the connector of the spiritual and the material so far as man is concerned. III THE WAY MIND THROUGH THE SUBCONSCIOUS MIND BUILDS BODY When one says that he numbers among his acquaintances some who are as old at sixty as some others are at eighty, he but gives expression to a fact that has become the common possession of many. I have known those who at fifty-five and sixty were to all intents and purposes really older, more decrepit, and rapidly growing still more decrepit both in mind and body, than many another at seventy and seventy-five and even at eighty.
