The self is not made manifest by those Pramanas (means of knowledge) by which objects susceptible of being cleft etc., are made manifest; hence It is unmanifest, being different in kind from objects susceptible to cleaving etc., It is inconceivable, being different in kind from all objects. As It does not possess the essential nature of any of them, It cannot even be conceived. Therefore, It is unchanging, incapable of modifications. So knowing this self to be possessed of the above mentioned qualities, it does not become you to feel grief for Its sake.
