A client asked me recently about the origins of crystals used in hypnosis so allow me to explain. It has been practiced since ancient times with the help of a crystal lobe, a pool of water, or any transparent object.
The main purpose of the objects are always to induce in the clairvoyant a state of hypnosis so the seer can see visions in the crystal. The reflection of light in the crystal forming points de repere for such hallucinations. Thus, the value of hypnotic ritual lies in its potential to affect the mind and imagination of the seer.
