वायुर्यथैको भुवनं प्रविष्टोरूपं रूपं प्रतिरूपो बभूव ।एकस्तथा सर्वभून्तरात्मारूपं रूपं प्रतिरूपो बहिश्च ॥
In plain words
One wind enters the world and becomes the shape of each thing it moves through — every form, its own answering form. In just that way the one inner Self of all beings becomes form after form, each one's own shape — and is outside them too.
Close to the Sanskrit
As the one wind, having entered the world, became of corresponding form with form after form, so the one inner Self of all beings became of corresponding form with form after form — and is outside as well.
