In plain words
...and a full hundred of them equal one who recites Rudra's mantra. A hundred of those Rudra-reciters equal one who reads the Atharvaśiras and its crest-chapter. A hundred of those readers equal one who recites the Mantrarāja, the king of mantras. And this is his reward: a supreme abode where the sun does not burn, where no wind stirs, where the moon gives no light, where no star shines, where fire does not consume, where death cannot enter, where sorrow has no place at all -- only bliss, unbroken and supreme, eternal, at peace, forever kind, the abode the yogis hold in their meditation. Once a yogi arrives there, he does not come back. This is what the ancient verse speaks of: 'That supreme step of Viṣṇu, the wise see always, like an eye spread wide across the sky. The inspired ones, awake and full of praise, keep it kindled -- Viṣṇu's own supreme step.' This is what belongs to the one free of desire. This is what belongs to the one free of desire.
Close to the Sanskrit
...and a full hundred [of ascetics] is equal to one reciter of Rudra['s mantra]; a hundred Rudra-reciters is one, and equal to that one is one reader of the Atharvaśiras-śikhā; a hundred readers of the Atharvaśiras-śikhā is one, and equal to that one is one reciter of the Mantrarāja. This indeed is that supreme abode of the reciter of the Mantrarāja, where the sun does not scorch, where the wind does not blow, where the moon does not shine, where the stars do not gleam, where fire does not burn, where death does not enter, where there is no sorrow -- ever-bliss, supreme bliss, eternal, at peace, ever-auspicious, praiser of Brahmā and the rest, the object of yogis' meditation -- where, having gone, the yogis do not return. This is declared by a Ṛgvedic verse: 'That supreme step of Viṣṇu the wise always see, like an eye stretched across the sky. The inspired ones, eager for praise, ever wakeful, kindle that -- the supreme step of Viṣṇu.' This becomes [the fruit] of one who is free from desire; this becomes [the fruit] of one who is free from desire.
