Note (return) — SA@NKARA'S INTRODUCTION (continued 3)

As therefore the individual soul and the highest Self differ in name only, it being a settled matter that perfect knowledge has for its object the absolute oneness of the two; it is senseless to insist (as some do) on a plurality of Selfs, and to maintain that the individual soul is different from the highest Self, and the highest Self from the individual soul. For the Self is indeed called by many different names, but it is one only. Nor does the passage, 'He who knows Brahman which is real, knowledge, infinite, as hidden in the cave' (Taitt. Up. II, 1), refer to some one cave (different from the abode of the individual soul)249. And that nobody else but Brahman is hidden in the cave we know from a subsequent passage, viz. 'Having sent forth he entered into it' (Taitt. Up. II, 6), according to which the creator only entered into the created beings.—Those who insist on the distinction of the individual and the highest Self oppose themselves to the true sense of the Vedânta-texts, stand thereby in the way of perfect knowledge, which is the door to perfect beatitude, and groundlessly assume release to be something effected, and therefore non-eternal250. (And if they attempt to show that moksha, although effected, is eternal) they involve themselves in a conflict with sound logic.
