Commentary:
The Supreme Self is one. It illumines the whole matter from the Unmanifested down to the blade of grass or a lump of clay, from the great elements down to firmness or fortitude. (Cf. verses 5 and 6.) Just as the sun is one, just as the sun illumines the whole world, just as the sun is not tainted, so also the Self is One in all bodies, It illumines all the bodies and It is not contaminated.
