What is the setting of Sacred Journey of the Peaceful Warrior by Dan Millman?

Sacred Journey of the Peaceful Warrior swiftly summarizes Dan Millman's life in Berkeley, Los Angeles, and Palo Alto CA, and Oberlin, OH, where in 1972 his five-year marriage falls apart, and he takes a summer off teaching to rediscover his "transcendent sense of freedom." Dan describes a few locales in "Sacred India," which he finds disappointing and heads home. During a stopover in Hawaii, he remembers the shaman that his Berkeley teacher, Socrates, predicts he will someday meet. Dan searches in Honolulu without success and is sitting on the sidewalk in a quandary when Ruth Johnson finds him.
