Looking to the body, superimposed by ignorance as the Self, ending with the skin, and making it the boundary, 'outside' is spoken; and looking to the inmost Self, making the body the boundary, 'inside' is spoken. When 'outside and inside' is said, a non-existence in the middle might be supposed; so it is said: unmoving and moving too. Even what appears as the moving and unmoving body is that very thing to be known, as the appearance of a snake is the rope. If it is unmoving and moving, then all the things to be known fall within the range of dealings; why, then, is it said that it is not known by all? True, it is the appearance of all; yet, like space, it is subtle, and because of its subtlety, in its own form, that thing to be known, though a thing to be known, is unknown to the ignorant. To the knowers it is ever known, by such means of knowledge as 'all this is the Self' (Chāndogya 7.25.2) and 'all this is Brahman' (Bṛhadāraṇyaka 2.5.1). Because it is unknown, it is far off, unreachable by the ignorant even in ten million years; and it is near, since it is the very Self of the knowers. Further.
