Lecture II-XI
If we consider that the human physical body was prepared for the human being during the ancient Saturn state, the etheric body during the Sun state, the astral body during ancient Moon, then we see how, in its way, this physical body is the most perfect member. It is the most evolved. If we could look into the miraculous structure of the physical heart, or the brain that is structured and organized with so much wisdom that physical science has not yet solved the riddles it presents, we would recognize this. The astral body is, indeed, a higher member but far less perfect; the etheric body has been perfected more than the astral but less than the physical. The I is the least perfect of all. For example, how little does the I understand the structures of the physical body. This is even precisely described in the Bible where it is said: “... then the Lord God formed man of dust from the ground and breathed into his nostrils the breath of life; and man became a living being ...” (Genesis 2:7) This happened during Lemurian times. At that time luciferic beings worked into the astral body of the human being. However, it was just by doing this, by slipping into the astral body that they caught up with what they themselves had neglected in the past. What they should have accomplished on the Moon they went through vicariously within the human being.
