Lecture V
Let us enquire which of these four principles is the oldest? It might easily be supposed that as the human ego is the highest, that which first makes man, man, it would be the oldest principle; but this is not the case. Neither the ego nor the astral body nor the etheric body was owned first by man, but the physical body—it is the oldest. The first rudiments of the physical body were formed as far back as on ancient Saturn, but you must not imagine that this body looked then anything like the body of today. When you consider the present physical body you observe in the first place something solid, a skeleton, that firmly constituted part described as “solid”; next you observe fluid constituents of many kinds; further, the physical body is permeated by air or gas; lastly, you find in it something which, considered occultly, is substantial—namely, warmth, inner warmth.
