For millennia humans have fasted for spiritual, emotional, and physical reasons--as a way to heal their bodies, reconnect to the sacred, regain a sense of life's purpose, and allow their souls to detoxify. We are evolutionarily designed to fast, and the body knows how to do it very well. Fasting allows the body and all its systems to rest, purify, and heal. During a fast, the body enters the same cleansing and healing cycle it normally enters during sleep. As a fast progresses, the body consumes everything that is not essential to bodily functioning--including bacteria, viruses, fibroid tumors, waste products in the blood, buildup around the joints, and stored fat--and the mind and heart release their toxic buildup as well. As Stephen Harrod Buhner reveals, in order to be truly transformed, you must first empty yourself. Offering step-by-step guidelines to fully prepare yourself for a deep fast, Buhner explores what to expect during and after spiritual, emotional, and physical fasting and detoxification. He details the necessary dietary and mental preparations leading up to your fast, what you can and can't do during a fast, and how to end your fast. He also explains how to plan the length of your fast and how to choose between a water fast, a juice fast, or a mono-diet fast. Revealing how fasting can help or heal many chronic conditions, such as type II diabetes, childhood seizures, hypertension, cardiovascular disease, arthritis, psoriasis, insomnia, and fibromyalgia, Buhner shows fasting as a way to truly inhabit the body, to experience its sacredness, and to activate its deep capabilities for self-healing.
