17. And on account of the statement of the way of him who has heard the Upanishads.
Other scriptural texts give an account of the way--the first station of which is light--that leads up to the highest Person, without any subsequent return, the soul of him who has read the Upanishads, and has thus acquired a knowledge of the true nature of the highest Self. Now this same way is described by the teacher to Upakosala in connexion with the instruction as to the Person in the eye, 'They go to light, from light to day,' &c. This also
proves that the Person within the eye is the highest Self.
