Mantra 10

वायुर्यथैको भुवनं प्रविष्टो रूपं रूपं प्रतिरूपो बभूव ।एकस्तथा सर्वभूतान्तरात्मा रूपं रूपं प्रतिरूपो बहिश्च ॥ १० ॥

In plain words

As wind, though one, having entered the world, becomes shaped to the likeness of every form -- so the one Self within all beings takes the likeness of every form, and yet remains outside.
