The notion of "Not-Two" is well known from the Indian Vedanta philosophy and in Buddhism but it is less known in Western philosophy. This paper shows how this notion can also be found in Nietzsche and develops it by examining Nietzsches famous formula "die ewige Wiederkunft des Gleichen". It is shown that each part of this formula has a more or less obvious double meaning. for which the small but significant difference between Wiederkunft and Wiederkehr is the best example, so that in the end we get almost two formulas, which are nevertheless neither one nor two. The methdoolgical guide-line of this examination is not only language but also the body as the necessary physical context to understand this formula.
