अथ येऽस्य प्रत्यञ्चो रश्मयस्ता एवास्यप्रतीच्यो मधुनाड्य. सामान्येव मधुकृतसामवेद एव पुष्प ता अमृता आप ॥
In plain words
Now, those rays of the sun that extend westward are its western honey-tubes. The Samans are the honey-makers, the Samaveda is the flower, and those rays are the immortal waters.
Close to the Sanskrit
Now, which are these backward rays of this [sun], those indeed are its western honey-tubes; the Samans themselves are the honey-makers, the Samaveda itself is the flower, those are the immortal waters.
