14. Thus the man knowing the knowable soul, knows himself as inaccessible to the feelings of pleasure and pain. Knowing this as certain, he finds the existence of no other thing, apart from what is contained in the container of his soul, which is as a thousandth part of a hair. This being ascertained, he views every thing in himself. With this certainty of knowledge, he comes to know his self as the reflector of all things, and present in all of them. After these ascertainments, he comes to the conclusion that he is not subject to pain or pleasure. Thus freed from anxieties, the mind freely exercises its powers over all customary duties, without being concerned with them.
