। ॥ १५९ ॥
In plain words
The Self exists as the witness of the body, its properties, its actions, its every state -- and simply because that witness exists at all, its utter distinctness from all of these is established on its own, needing no further proof.
Close to the Sanskrit
The distinctness of the Self, who indeed exists as the witness of the body, its properties, its actions, and its states, is self-evidently established.
