He obtains here the victory over the sun (death), and there is a higher victory than the victory over the sun for him, who knowing this meditates on the sevenfold Sâman as uniform in itself, which leads beyond death, yea, which leads beyond death.

In plain words: A person who understands this and meditates on the seven-part chant (the Sâman, a sacred sung hymn) as one whole wins victory over death, pictured here as the sun. He also gains something even higher, a victory that carries him beyond death.
