What is the setting of The Tenth Insight: Holding the Vision by James Redfield?

The action of the narrative unfolds, after a brief introductory chapter, in various locations within a mountain valley - a cave, a forest, a waterfall and pool, by the banks of a river. There are two levels of value to be considered here. The first is on a relatively superficial level, and has to do with the sense of wildness, of isolation, and of danger the environment presents. In other words, simply being in this place is a physical risk, an obstacle to functioning without Fear (which, as the narrative maintains, is the fundamental purpose of existence and the goal to enlightenment).
