आप्नोती हादित्यस्य जयं परो हास्यादित्यजयाज्जयो भवति य एतदेवं विद्वानात्मसंमितमतिमृत्यु सप्तविधं सामोपास्ते सामोपास्ते ॥ २.१०.६ ॥
In plain words
He wins the victory of the sun, and his victory is higher than the victory of the sun, who knowing this worships the sevenfold Sāman that is measured within itself and leads beyond death — worships the Sāman.
The commentators

उक्तस्यैव पिण्डितार्थमाह—
एकविंशतिसङ्ख्यया आदित्यस्य जयमनु, परा ह, अस्य एवविद् आदित्यजयात् मृत्युगोचरात् परो जयो भवति, द्वाविशत्यक्षरसरूपयेत्यर्थ । य एतदेवं विद्वानाित्याद्युक्तार्थम्, तस्यैतद्यथोक्त फलमिति । द्विरभ्यास साप्तविध्यसमाप्त्यथ ॥
In plain words
Now the author states the condensed essence of what has just been explained.
Through the count of twenty-one, following the conquest of the sun, there arises for the knower a supreme victory that transcends even the sphere of death—signified by the twenty-two syllabic form. For one who understands this in the manner already explained, this is the fruit attained. The repetition is prescribed to fulfill the completion of the sevenfold meditation.
Close to the Sanskrit
(The author) states the condensed meaning of just what has been said.
By the twenty-first number following the conquest of the sun, indeed, a higher victory over the realm of death becomes for this knower, meaning by the form of twenty-two syllables. Who knows this thus, the aforementioned meaning, for him this is the stated fruit. The doubling is for the completion of the sevenfold character.
