Questions Regarding Health in Light of Spiritual Science

When we look at this physical-spiritual effect, we will see what the source of the physical and etheric is: that our astral body is the actual creator of the physical and etheric. The physical is only a condensation of the spiritual, and the spiritual can in turn have an effect on the physical, so that it is worked through and lived through in the right way. Then, when we consider the basic idea of such a thing, we can also hope to understand — through having a science that points out how the spiritual-soul lives in human beings — that what lives in the spiritual-soul is expressed in health and illness in the physical.
