27. He who knows what is the support of that Sâman, he is supported. Now verily its support is speech only. For, as supported in speech, that breath is sung as that Sâman. Some say the support is in food. Next follows the Abhyâroha (the ascension) of the Pavamâna verses. Verily the Prastotri begins to sing the Sâman, and when he begins, then let him (the sacrificer) recite these (three Yagus-verses): 'Lead me from the unreal to the real! Lead me from darkness to light! Lead me from death to immortality!' Now when he says, 'Lead me from the unreal to the real,' the unreal is verily death, the real immortality. He therefore says, 'Lead me from death to immortality, make me immortal.' When he says, 'Lead me from darkness to light,' darkness is verily death, light immortality. He therefore says, 'Lead me from death to immortality, make me immortal.' When he says, 'Lead me from death to immortality,' there is nothing there, as it were, hidden (obscure, requiring explanation).
