The Language of Anthroposophy
"The seer realizes what anthroposophy is in a deeper sense. It is the language that will be spoken by the living and the dead, by those who live in the physical world and those who dwell between death and rebirth.
Souls who remain behind and have acquired thoughts about the super-sensible worlds can be seen by the dead. If they have radiated love before death, they can also do so after death. This carries the conviction that anthroposophy is a language that renders it possible for those in super-sensible realms to perceive the events of the physical world.
The prospect that stands before humanity is that souls will become even more lonely, will be unable to find a bridge to one another, unless a link is forged from soul to soul by means of spiritual concepts. That is the reality of anthroposophy, for it is not a theory."
