There are germs and impurities, but there are also elements to purify them. Those five elements, earth, water, fire, air, and ether, as spoken of by the mystics, do not only compose germs, but can also destroy them, if one only knew how one could make use of those five elements to purify one's body with them and also one's mind. As there is need of sun and water for plants to grow, so there is need of the five elements for a person to keep in perfect health.
