In the world of shadows definite identities are illusory. It is the world of borderlines: the
borderline obviously, between light and darkness, but also the borderline between what
exists and what does not, and the borderline between the separateness of the individual
objects and the wholeness of the dark which forms as shadows merge. Shadow World
evolves continuously: old patterns disintegrate and their remnants constantly form into
new but strangely familiar ones. In the world of shadows nothing is as we have always
believed it to be.
