जगद्विलक्षणं ब्रह्म ब्रह्मणोऽन्यन्न किंचन ।ब्रह्मान्यद्भाति चेन्मिथ्या यथा मरुमरीचिका ॥ ६३ ॥
In plain words
Brahman is of an entirely different order than this world; apart from brahman there is not one thing. And if something other than brahman does appear — it is mithyā, false, like water shimmering across the desert.
Close to the Sanskrit
Brahman is distinct from the world; other than brahman there is not anything whatever. If something other than brahman appears, it is false — as the mirage in the desert.
