सुवर्णाज्जायमानस्य सुवर्णत्वं च शाश्वतम् ।ब्रह्मणो जायमानस्य ब्रह्मत्वं च तथा भवेत् ॥ ५१ ॥
In plain words
Whatever is made out of gold is gold, and stays gold. So whatever is born of Brahman is Brahman — it cannot be otherwise.
Close to the Sanskrit
Of that which is born from gold, goldness is perpetual; of that which is born from Brahman, Brahman-ness likewise must be.
