The Yogi takes the student when the latter is much bothered by a consideration of some knotty and perplexing philosophical subject. He bids the student relax every muscle,--take the tension from every nerve--throw aside all mental strain, and then wait a few moments. Then the student is instructed to grasp the subject which he has had before his mind firmly and fixedly before his mental vision, by means of concentration. Then he is instructed to pass it on to the sub-conscious mentality by an effort of the Will, which effort is aided by forming a mental picture of the subject as a material substance, _or bundle of thought,_ which is being bodily lifted up and dropped down a mental hatch-way, or trap-door, in which it sinks from sight. The student is then instructed to say to the sub-conscious mentality: "I wish this subject thoroughly analyzed, arranged, classified (and whatever else is desired) and then the results handed back to me. Attend to this." The student is taught to speak to the sub-conscious mentality just as if it were a separate entity of being, which had been employed to do the work. He is also taught that _confident expectation_ is an important part of the process, and that the degree of success depends upon the degree of this confident expectation. In obstinate cases, the student is taught to use the Imagination freely, until he is able to make a mental image or picture of the sub-conscious mind doing what is required of it. This process clears away a mental path for the feet of the sub-conscious mind, which it will choose thereafter, as it prefers to follow the line of least resistance. Of course much depends upon practice--practice makes perfect, you know, in everything else, and sub-consciousing is no exception to the rule. The student gradually acquires a proficiency in the art of sub-consciousing, and thereafter devotes his time to acquiring new facts for mental digestion, rather than bestowing it upon the mechanical act of thinking. But a very important point to be remembered is that the Will-power back of the transferred thought-material, which Will-power is the cause of the subconscious action, depends very greatly upon the attention and interest given to the acquired material. This mass of thought-material which is to be digested, and threshed out by the sub-conscious mind, must be well saturated with interest and attention, in order to obtain the best results. In fact interest and attention are such important aids to the Will, that any consideration of the development and acquirement of Will-power is practically a development and acquirement of attention and interest. The student is referred to previous lessons in this course in which the importance of interest and attention is explained and described.
