II. Introductory Explanations Concerning the Nature of Man

When I say that man's etheric body resembles his physical body, I mention a fact which must be borne in mind and which must be mentioned here, for it will give rise to important conclusions in following lectures. This statement must be subjected to an important limitation, for in reality the etheric body differs greatly from the physical body and resembles it only in its upper part, in the head; but it differs from it greatly in regard to the fact that it is of opposite sex: man's etheric body is feminine, and woman's etheric body is masculine. Every human being is therefore bisexual; the sex of the physical body is only an external expression, having its opposite pole in the etheric body. Even as a magnet has a north pole and a south pole, even as a magnet cannot have only a north pole, so we also find two poles in man: the pole and the counter-pole.
