स्वयमन्तर्बहिर्व्याप्य भासयन्नखिलं जगत् ।ब्रह्म प्रकाशते वह्निप्रतप्तायसपिण्डवत् ॥ ६२ ॥
In plain words
Filling everything by its own being, inside and out, lighting up the whole world — Brahman shines. Like an iron ball heated right through with fire.
Close to the Sanskrit
Itself, having pervaded within and without, illuminating the entire world, Brahman shines forth — like a lump of iron thoroughly heated by fire.
