Poetry is a sort of inspired mathematics, which gives us equations, not for abstract figures, triangles, squares, and the like, but for the human emotions. If one has a mind which inclines to magic rather than science, one will prefer to speak of these equations as spells or incantations; it sounds more arcane, mysterious, recondite.
Ezra PoundThe flavors of the peach and the apricot are not lost from generation to generation, neither are they transmitted by book learning. The mystic tradition, any mystic tradition, is of a similar nature, that is, it is dependent on direct perception, a 'knowledge' as permanent as the faculty for receiving it.
