The Etheric Body as a Reflexion of the Universe

Now it must be evident to everyone of us that the etheric body of a man who died young must have an entirely different constitution than that of a man who died after having reached, so to speak, a normal age. We know that the ordinary natural science of to-day always speaks of the fact that forces never go lost, but transform themselves. Natural science recognises this truth in regard to the external world of physical life; it admits that forces do not go lost, but merely transform themselves. Spiritual science must teach that this truth should be recognised in regard to the spiritual world.
