Now with reference to the body: Speech is the Rik and the prana is the Saman. This Saman (the prana) rests on that Rik (speech). Therefore the Saman is sung, resting on the Rik. Sa is speech, ama is the prana; thus they (speech and the prana) are designated as Sama.

The ear is the Rik and the mind is the Saman. This Saman (the mind) rests on that Rik (the ear). Therefore the Saman is sung, resting on the Rik. Sa is the ear, ama is the mind; thus they (the ear and the mind) are designated as Sama.

Now, the white radiance of the eye is the Rik and its blue intense darkness is the Saman. This Saman (darkness) rests on that Rik (radiance). Therefore the Saman is sung, resting on the Rik.

Now, the person who is seen in the eye is the Rik, he is the Saman, he is the Uktha, he is the Yajus, he is Brahman. The form of this person in the eye is the same as the form of that person in the sun. The joints this person in the eye are the same as the joints of that person in the sun; the name of this one (Ut) is the same as the name of that one.
