Lecture II

It is necessary for us to be clear about these things for it is only then that that we learn under what illusion present day thinking labours, with what a host of illusions this thinking fools itself, and how the only cure for this must be effected through that knowledge so difficult to acquire which, we trust, does not fail to take the physical body into consideration. For when going about in the physical body we must have solid earth beneath our feet: When thinking in the physical world we must have support for our thinking; we must have a nervous system. When, however, we change the place of our thinking activity to our astral body, the etheric body will become for us what the physical body is when we think with the etheric body.
