*Important Precaution: Fasting can cause weakness, tiredness and on rare occasion, fainting. If you aren’t sure how fasting affects your body, proceed with caution. Seniors, and those on medication, should check with a doctor before fasting, and consider a less stringent form of fasting. Retreat also involves many prostrations which can be taxing on the body. Keep in mind that fasting can affect your capacity to do prostrations or other physical activity. All practices during the retreat are flexible and practitioners should pay attention to their limits and alter their practice as needed.
