That is not to say, however, that there are not strange faculties lying latent in the human mind. On the contrary, because mentalism is a fact in Nature, most successful yogis discover that some extraordinary faculties automatically arise in them. They offer a fascinating field of exploration to a properly trained competent investigator who has not only mastered the subject in a rational manner, and knows enough of the dangers and risks attending it, not only disciplined his mind and desires through the scientific, metaphysical, and yogic courses, but also consciously brought his ego within the framework of universal being. But amateurs who invade this field through motives of mere curiosity or immoral exploitation sooner or later discover that it becomes a region either of sheer time-wasting or else of grave danger. Even the best of men will find his way through this field with the utmost difficulty, while for most dilettanti it is an undertaking which is usually foredoomed to failure. In any case these powers not only are hard to get but may prove dangerous when gotten.
