“There are two kinds of flesh. The flesh of _Adam_ (the physical body) is gross earthly flesh; the flesh that is _derived from Adam_ is of a subtle kind. It is not made of gross matter, it penetrates through all walls without requiring doors or holes; nevertheless both kinds of flesh have their blood and bones, and both differ again from the spirit.” (_Paracelsus_, “De Nymphis.”) Man having within himself the same essences and powers, and there being only one universal law of evolution, there takes place in him a development similar to, if not identical with, the development in eternal and internal nature. Accords and discords in his nature can grow and swell into harmonies or disharmonies, and constitute the whole man a symphony or cacophony, colouring his whole being and transmitting this to his offspring. A seed of wheat and a seed of barley resemble each other, and nevertheless wheat grows out of one and barley out of the other. The _ovum_ of a human being shows no essential difference from that of a monkey; nevertheless out of the one grows a human being and out of the other a monkey. The nature of man is fully expressed in every part of his organism, and in the sperm of the father is contained not only the quality of this or that part of his nature, but the potentiality of the whole.[34] The quality of the constitution of a man determines the length of his natural life. “If a child is born, its _firmament_ (astral body and mind, etc.) is born with it, containing the seven principles, of which each has its own potencies and qualities. What is called ‘_predestination_’ is only the quality of the powers in man. The weakness or strength of his constitution determines whether his life is to be short or long, according to natural laws; the planets in him run their course whether he has a long or a short life, only in the former case the course of his planets is of a longer, and in the other case of a shorter duration. The quality of the constitution which a man receives at his birth determines the length of his natural life, just as the quantity of sand in an hour glass determines the time when it will have run down.” (“Paramirum,” L. I., Tr. iii., C. 5.) The _Ens Naturæ_ therefore refers to those beginnings in man’s constitution which are the result of the quality of his body, soul and mind as he received them from nature, and includes all inherited physical diseases, qualities of temperament and mental peculiarities; for the earthly part of the mind (_Káma Manas_) belongs to terrestrial nature and its tendencies are inherited; while the spiritual part of the mind (_Manas Buddhi_) is not inherited from the parents, but belongs to the spiritual man whose parent exists in eternity.[35]
