The true adept does not sell either the secrets of his knowledge or the use of his powers. There are several reasons for this. The most important is that he would harm himself for he would lose the link with the very source of his knowledge and power. He does not possess them in himself but by virtue of being possessed by the Higher Self. From the moment that he attempted to make them a means of worldly profit, It would gradually begin to desert him. Another reason is that he would lose his privileged position to speak the pure truth. To the extent that he had to rely upon purchasers of it, to that extent he would have to shape it or conform it to their tastes and prejudices; otherwise they would refuse to have it. He would have to use his powers to please them. He would have to accommodate his knowledge to their weaknesses. He could succeed in the profession of teaching truth only by failing in his own duty of realizing truth. For the truth being the one thing he got without price, is the one thing which he must give without price. This is the law governing its distribution. Anyone who violates it proves by this very violation that he does not possess truth in all its shining purity.
