What are the motifs in The Teachings of Don Juan: A Yaqui Way of Knowledge by Carlos Castaneda?

Reality is a recurring idea. The Teachings of Don Juan deals with multiple realities coexisting and overlapping. Apprentice Carlos Castaneda, as a good Westerner, demands to know how it looks when he flies or transforms into a crow; but his master, Don Juan Matus, declares this is unimportant. What he feels is reality as he visits the allies or Mescalito. No rational explanations are possible. In "non-ordinary reality" visions can be halted and studied for indefinite periods. Details come as single items, isolated from one another, and appear sequentially.
