योनिश्च हि गीयते ॥ २७ ॥
yoniśca hi gīyate || 27 ||
yoniḥ—Origin; ca—and; hi—because; gīyate—is called.
27. And because (Brahman) is called the origin.
“That which the wise regard as the origin of all beings” (Mu. 1. 1. 6)—this shows that Brahman is the material cause of the world. Hence Its being the material cause is established.
