Mysticism is the practice of religious experiences during different consciousness states. This is accompanied by pertinent beliefs, ethics, rituals, myths, magic, and legends. “Mystic” came from the Greek verb “myein” which means “to close” (particularly the eyes or mouth). Thus, the Greek noun “mystes” pertains to a person who keeps a secret. Mysticism originally referred to a secret cult or a mystery religion with secret rites.
Currently, mysticism is defined as engaging in activities which aim to have a close encounter with a Supreme Being. For instance, Pentecostals believe that faith and salvation should be powerfully experienced and one of the evidences is the infilling of the Holy Ghost which is manifested by speaking in tongues. Their worship is energetic and dynamic, for instance, they may dance or run in the Spirit.
