The root-matter of this great knowledge is not to be found in books; we must seek it in ourselves by means of deep meditation, discovering the sacred fire in its proper source. . . This is why I have written nothing concerning these revelations and shall never even speak about them. Whosoever shall undertake to popularize them will find the attempt futile, for, except in the case of a very small number of men who have been endowed with understanding from God to discern these heavenly truths within themselves, it will render them contemptible to some, while filling others with vain and rash self-confidence, as if they were depositaries of marvels which they do not understand all the same.
