Two fragments by Nietzsche written 1882-3:
I do not want my life to start again. How did I manage to bear it? By creating. What is it that allows me to bear its sight? Beholding the overman who affirms life. I have attempted to affirm it myself — Alas.
The instant in which I created the return is immortal, it is for the sake of that instant that I endure the return.
In a very fine article, Paolo D'Iorio comments: Nietzsche, the man of knowledge had attained the climax of his life at the very instant in which he had grasped the knowledge he regarded as the most important of all. When, at the end of his life, he became aware of having attained this summit, he ceased to need an alter ego in order to affirm the life that forever returns and as a conclusion to the Twilight of the Idols, which are the very last lines published in his lifetime, he let these words be printed: ―I, the last disciple of the philosopher Dionysus,—I the master of the eternal return.
