सर्वं जगदिदं नाहं विषयत्वादिदंधियः ।अहं नाहं सुषुप्त्यादौ अहमः साक्षितः सदा ॥ ३९ ॥
In plain words
None of this world is me. All of it shows up as an object, something the mind points at and calls 'this'. And the 'I' is not me either — it goes missing in deep sleep, while I stay on, watching it, always.
Close to the Sanskrit
All this world is not I, because of being the object of the 'this'-cognition. The 'I' is not I either — in deep sleep and the rest — since [I am] always the witness of the 'I'.
