Not merely a work of Hinduism (indeed one that partly omits it), DeLaurence has here managed to compile astral travel, scrying, crystal gazing, telepathy, and much more into a single Victorian volume. Known for his ads within the context of occult texts, DeLaurence should not be judged as the showman he was in order to survive in a cut-throat and bloated occult literary world, but rather as a visionary whose relevance persists to this day.
