Now an explanation with reference to the body: Speech is Ṛk, and prāṇa is Sāma. This Sāma (called prāṇa) is based on the Ṛk (called speech). This is why Sāma scholars sing songs based on the Ṛk. Speech is sā, and prāṇa is ama. Together they are Sāma.
The eyes are like the Ṛg Veda, and the self (i.e., the form seen in the eyes) is like the Sāma, which is based on the Ṛk. This is why the Sāma is sung based on the Ṛk. The eyes are the sā, and the self (the form in the eyes) is the ama. The two together are Sāma.
The organ of hearing is the Ṛk, and the mind is Sāma. This Sāma (called the mind) is based on the Ṛk (called the organ of hearing). This is why Sāma scholars sing songs based on the Ṛk. The organ of hearing is sā, and the mind is ama. Together they are Sāma.
Further, there is a white glow in the eyes, and this is compared with the Ṛg Veda. Then there is a similar glow which is a deep, dark blue. This is compared to the Sāma Veda. This dark glow is based on the white glow. This is why the Sāma is said to be based on the Ṛk. Sā of Sāma stands for the white glow in the eye, and ama stands for the deep blue glow. These two together are Sāma.
The person seen in the eye is the Ṛk, the Sāma, the uktha (a part of the Sāma), and the Yajus. He is also the three Vedas. The person who is in the sun and the person who is in the eye are the same. The same two singers (i.e., the Ṛk and the Sāma) sing in praise of each of them, and they have the same names.
The person in the eye rules the world below him and also rules the desires of the human mind. Those who sing accompanied by the vīṇā, are, in fact, singing in his honour. This is why such musicians become wealthy.
(This is what a worshipper achieves) He who knows the Truth mentioned above (i.e., the Truth about Āditya, the sun), sings the Sāma in honour of both Āditya and the person in the eye. He then becomes one with Āditya. Not only that, but he also attains mastery of the planes above Āditya and attains everything the gods and goddesses wish for. (In other words, such a person becomes divine).
Now, (the same worshipper) also attains, by the grace of the Lord in the eye, all the worlds below that Lord. Again, he attains all that human beings may desire. This is why the singer will ask:
(A learned udgātā, who sings the Sāma, will ask the person for whose benefit he is singing) ‘What shall I ask for on your behalf through my songs?’ He says this (because he knows the Lord in the eye presides over the Sāma and is capable of granting whatever the person wants) and he sings the Sāma, he sings the Sāma.
