One might ask: "What is reason? Where does it belong?" Reason belongs to both earth and heaven: its depth heavenly, its surface earthly; and that which, in the form of reason, fills the gap between earth and heaven is the middle part of it which unites them. Therefore reason can be most confusing, and reason can be most enlightening. In the language of the Hindus reason is called Badhi, or Buddh, from which comes the title of Gautama Buddha. But what reason is this? It is the depth of reason, the most perfect reasoning which belongs to heaven.
