Lecture XI
Hence a true initiate must have the right attitude of soul for the spiritual world, but he must also feel fully responsible for the fact that the moment he returns to the physical world he has to work with physical concepts. A medium cannot do this because he doesn't leave his body consciously. When he comes back again his ego and astral body fill the physical and etheric bodies with a line of thought which is no doubt appropriate for the spiritual world, but it corrupts all moral feelings in the physical world. Hence mediums become corrupted, and the corruption with respect to truth and lies then' extends to other forms of corruption. Hence the fact is that Babylon went through this development from the greatest revelations of spiritual worlds to a terrible corruption; first with respect to the principle of spiritual revelation, and then also with respect to human life in general, so that the previous corruption in the spiritual sphere extended to the latter. This spiritual corruption is very powerful; so that someone becomes more immoral if he becomes corrupt after he has gone into spiritual realms than he did before with his ordinary human tendencies. This is why Babylon was considered to be a representative of moral corruption.
