Philosophy rejects such psychic, occult, mediumistic, or trance experiences when imagination runs unbraked into them, or emotion heaves hysterically in them. It is then time to stop the dangerous tendency by applying a firm will and cold reason. Philosophy welcomes only a single mystic experience--that of the Void (Nirvikalpa Samadhi), where every separate form and individual consciousness vanishes, whereas all other mystic experiences retain them. This is the difference.
