 These five representations are not competing models, and in fact often overlap one another. For instance, the principles that operate in the cosmos and the inner deities that personify those principles are to a large extent equivalent: one may understand and represent those principles in abstract terms, in deified forms, or simultaneously in both ways. Certain aspects of the cosmological and the alchemical models are identical. Similarly, illustrations of the body as a landscape also include the palaces that function as headquarters for the administration of the body (Huang 2012: id.).
