Thus Spoke Zarathustra
Thus Spoke Zarathustra: A Book for All and None is a philosophical novel by German philosopher Friedrich Nietzsche, composed in four parts written between 1883 and 1885 and published between 1883 and 1891. Much of the work deals with ideas such as the "eternal recurrence of the same", the parable on the "death of God", and the "prophecy" of the Übermensch, which were first introduced in The Gay Science.

Context: But the worst enemy you can meet will always be yourself; you ambush yourself in caverns and forests. You solitary one, you go the way to yourself! And your way leads you past yourself and your seven devils! You will be a heretic to yourself, and a sorcerer and a soothsayer, and a fool, and a doubter, and a reprobate, and a villain. You must be ready to burn yourself in your own flame; how could you rise anew if you have not first become ashes!
