यस्मिन्सर्वाणि भूतानि ह्यात्मत्वेन विजानतः ।न वै तस्य भवेन्मोहो न च शोकोऽद्वितीयतः ॥ ५४ ॥
In plain words
All beings, held in that Self and known as the Self itself: for the one who knows them so, no delusion can arise, and no grief either — because there is no second thing anywhere.
Close to the Sanskrit
In which all beings — indeed, for the one who knows them as the Self — for him there would arise no delusion, and no sorrow either, because there is no second.
