What metaphors are used in Where the Air Is Clear by Carlos Fuentes?

Ixca and Rodrigo Pola talk about the need for a connection to a larger power, using highly metaphorical language. Responsibility to one's own creation is essential, says Ixca, referring both creation in both a parental and a divine sense. If god is linked to creation, and creation contains evil, doesn't god then contain evil, asks Pola? Ixca tells him "if god is infinite good, Rodrigo, then he is also infinite evil; he is the perfect mirror of all that he created." Our destiny, he goes on, must fulfill itself in one of these two realities, he asserts.
