Dann entzündeten die Götter das [Feuer] im innersten ihrer Seele. |
Und nachdem sie dieses unsterbliche Element im innersten ihrer Seele entfacht hatten erlangten sie Unsterblichkeit und Unbesiegbarkeit. Sie überwanden ihre sterblichen und besiegbaren Feinde.
Und sofern [ein Mensch] das unsterbliche Element in seinem Innersten entfacht erlangt er die volle Spanne seines Lebens, da es für ihn keine Hoffnung auf wahre Unsterblichkeit gibt.
Wahrlich wird er unbesiegbar, und seine Feinde können ihn nicht überwinden, obwohl sie ihn zu bezwingen trachten.
Und natürlich, wenn einer mit entfachtem inneren Feuer mit einem, der sein inneres Feuer nicht entfacht hat miteinander kämpfen, dann besiegt der mit innerem Feuer den anderen.
Wahrlich, er wird so unbesiegbar, er wird so unsterblich.

Englische Übersetzung von Julius Eggeling:

The gods then established that (fire) in their innermost soul; and having established that immortal element in their innermost soul, and become immortal and unconquerable, they overcame their mortal, conquerable enemies. And so this one now establishes that immortal element in his innermost soul; and--though there is for him no hope of immortality--he obtains the full measure of life; for, indeed, he becomes unconquerable, and his enemy, though striving to conquer, conquers him not. And, accordingly, when one who has established his fires and one who has not established his fires, vie with each other, he who has established his fires overcomes the other, for, verily, he thereby becomes unconquerable, he thereby becomes immortal.
