It's a quick overview kind of read, Swami doesn't go into detailed specifics for teaching these methods, but it looked interesting for a book written almost 100 years ago. Many of his ideas align very closely with RB's work... an astral body that corresponds with a physical body, visiting the Akashic records, viewing of an aura, a "pranic" aura that correponds to RB's etheric aura, etc.
