The true foundation of all culture is the knowledge and understanding of water. Water is the ur-substance or ur-cause of all creation and for this reason is the ur-original accumulator, which readily absorbs both earthly and cosmic substances and conveys them to the body in a purely objective form. This must be done in such a way that the ur-attributes will in no way be modified and that change as such can only first come about in the effect, which the organically correctly structured body mediates and imparts. For this reason a good spirit dwells in a healthy body. Conversely a body full of vitality can be created, maintained and further developed by healing the inhering spirit.
