30. And there is no objection, since (the quality of knowledge) exists wherever the Self is; this being observed.

Since knowledge is an attribute which is met with wherever a Self is, there is no objection to the Self being designated by that attribute. Similarly we observe that special kinds of cows, as e.g. hornless ones, are designated by the term 'cow,' since the quality of possessing the generic character of cows is met with everywhere in connexion with the essential character of such animals with mutilated horns; since in fact that quality contributes to define their essential character. The 'and' of the Sûtra is meant to suggest a further argument, viz. that to apply to the Self the term 'knowledge' is suitable for that reason also that like knowledge the Self is self-illuminated. The objection that knowledge or consciousness cannot be an attribute inseparably connected with the essential nature of the Self as there is no consciousness in deep sleep and similar states is taken up in the next Sûtra.
