Hypnotism, mesmerism, and spiritualism are interrelated practices that explore the power of the human mind and unseen forces beyond ordinary perception. Hypnotism involves inducing a trance-like state in which a person becomes highly suggestible and open to guidance or healing, often used for therapeutic or investigative purposes. Mesmerism, developed by Franz Anton Mesmer, is based on the idea of a universal magnetic fluid that can be manipulated to restore balance and cure ailments through passes of the hands or focused intention. Spiritualism, on the other hand, centers on communication with spirits of the deceased through mediums, séances, and psychic phenomena, seeking to prove the continuity of life after death. Together, these practices reflect humanity’s enduring fascination with the mysteries of consciousness, energy, and the spiritual dimensions of existence.
