यश्चन्द्रतारके तिष्ठंश्चन्द्रतारकादन्त-रो यं चन्द्रतारकं न वेद यस्य चन्द्रतार-कँ शरीरं यश्चन्द्रतारकमन्तरो यमयत्ये-ष त आत्मान्तर्याम्यमृतः ॥ ११ ॥
In plain words
The one who lives inside the moon and every star, yet is nothing they can claim as their own, whom the moon and the stars never know, whose body they are, who governs them from within -- that is your self, the ruler seated inside everything, and death does not touch him.
Close to the Sanskrit
He who, dwelling in the moon and the stars, is other than the moon and the stars, whom the moon and the stars do not know, whose body the moon and the stars are, who controls the moon and the stars from within -- he is your self, the inner controller, immortal.
