Our adventure into the Hatha Yoga Pradipika has brought us to the cleansing practices. Shatkarma, of which there are 6, is the practice of cleansing the physical body in preparation for deepening the practice.
Keep in mind that when the pradipika was written, the people of the time suffered from far more ailments than we face today. Their practices of bhasti, dauti and nauli as well as others were not just for enlightenment preparedness but also an attempt to prevent themselves from suffering disease or death.
As we venture further into this text, please remember that these practices are not for everyone. Today we have medical science and trained professionals who can evaluate our bodies inside and out. If you are considering attempting the shatkarmas please consult with a professional beforehand.
