Keys to Perception: A Practical Guide to Psychic Development by Ivo Dominguez Jr.

Ivo Dominguez Jr. presents an exercise-based approach to psychic perception in Keys to Perception. The book draws on his teaching experience and introduces practices involving chanting, crystals, chakras, herbs and oils, along with a version of the Middle-Pillar Ritual.

Its focus is developing and interpreting experiences understood as psychic within magical and spiritual traditions. Those claims reflect the author's framework; the exercises do not establish scientifically proven extrasensory abilities.
