Create Harmony
"The whole of waking life is a process destructive of the physical body. Illnesses are caused by excessive activity of the astral body. Eating to excess affords a stimulus to the astral body which re-acts in a disturbing way on the physical body. That is why fasting is laid down in certain religions. The effect of fasting is that the astral body, having greater quiet and less to do, partially detaches itself from the physical body. Its vibrations are modulated and communicate a regular rhythm to the etheric body. Rhythm is thus set going in the etheric body by means of fasting. Harmony is brought into life (etheric body) and form (physical body). In other words, harmony reigns between the universe and man."Fasting is an intense experience of strengthening the will. One releases one's own desires for earthly comfort and pleasures in exchange for spiritual fulfillment. Consider doing it regularly! A 3-day fast helps deepen one's experience of the anthroposophical festivals and alignment with the rhythms of the seasons. Intermittent fasting is helpful for ongoing maintenance.
