सर्गं वक्त्यस्य तस्माद्वा एतस्मादित्यपि श्रुतिः ।सकाशाद्ब्रह्मणस्तस्मादनित्यत्वे न संशयः ॥ १९ ॥
In plain words
Scripture itself speaks of this thing's being produced — "from that, indeed, from this very One..." — so it runs. It comes from that Brahman; that it is not eternal admits of no doubt.
Close to the Sanskrit
Śruti too declares the creation of this, [saying] 'from that, indeed, from this...'; since [it arises] from the presence of that Brahman, there is no doubt regarding [its] non-eternality.
