For only to those who often approach them, and have given them a trial by faith and in their whole life, will they supply the real philosophy and the true theology. They also wish us to require an interpreter and guide. For so they considered, that, receiving truth at the hands of those who knew it well, we would be more earnest and less liable to deception, and those worthy of them would profit. Besides, all things that shine through a veil show the truth grander and more imposing; as fruits shining through water, and figures through veils, which give added reflections to them. For, in addition to the fact that things unconcealed are perceived in one way, the rays of light shining round reveal defects. Since, then, we may draw several meanings, as we do from what is expressed in veiled form, such being the case, the ignorant and unlearned man fails. But the Gnostic apprehends. Now, then, it is not wished that all things should be exposed indiscriminately to all and sundry, or the benefits of wisdom communicated to those who have not even in a dream been purified in soul, (for it is not allowed to hand to every chance comer what has been procured with such laborious efforts); nor are the mysteries of the word to be expounded to the profane.
