Imaginal fasting is a practice inspired by the teachings of Selene Calloni Williams is based on the principles of macrobiotics and the ancient initiations practiced during the Eleusinian, Orphic and Dionysian mysteries. This practice involves a nine-day path of death and rebirth, during which the amount of food ingested is gradually reduced. In the middle, fourth, fifth and sixth days, a liquid fast is reached, during which the body is purified thanks to soups, centrifuges and herbal teas. Over the next few days, food is slowly reintroduced.
