” ‘Learn to separate the fine from the coarse’ — this principle from the ‘Emerald Tablets of Hermes Trismegistus’ refers to the WORK OF THE HUMAN factory, and if a man learns to ‘separate the fine from the coarse,’ that is, if he brings the production of the fine ‘hydrogens’ to its possible maximum, he will by this very fact create for himself the possibility of an inner growth which can be brought about by no other means. Inner growth, the growth of the inner bodies of man, the astral, the mental, and so on, is a material process completely analogous to the growth of the physical body. In order to grow, a child must have good food, his organism must be in a healthy condition to prepare from this food the material necessary for the growth of the tissues. The same thing is necessary for the growth of the ‘astral body’; out of the various kinds of food entering it, the organism must produce the substances necessary for the growth of the ‘astral body.’ Moreover, the ‘astral body’ requires for its growth the same substances as those necessary to maintain the physical body, only in much greater quantities. If the physical organism begins to produce a sufficient quantity of these fine substances and the ‘astral body’ within it becomes formed, this astral organism will require for its maintenance less of these substances than it required during its growth. The surplus from these substances can then be used for the formation and growth of the ‘mental body’ which will grow with the help of the same substances that feed the ‘astral body,’ but of course the growth of the ‘mental body’ will require more of these substances than the growth and feeding of the ‘astral body.’ The surplus of the substances left over from the feeding of the ‘mental body’ will go to the growth of the fourth body. But in all cases the surplus will have to be very large. All the fine substances necessary for the growth and feeding of the higher bodies must be produced within the physical organism, and the physical organism is able to produce them provided the human factory is working properly and economically.

“We have followed the development of two octaves. The third octave, that is, the octave of impressions, begins through a conscious effort. Do 48 passes to re 24; re 24 passes to mi 12. At this point the development of the octave comes to a stop. “Now if we examine the result of the development of these three octaves, we shall see that the first octave has reached si 12, the second la 6, and the third mi 12. Thus the first and third octaves stop at notes which are unable to pass to the following notes. “For the two octaves to develop further, a second conscious shock is needed at a certain point in the machine, a new conscious effort is necessary which will enable the two octaves to continue their development. The nature of this effort demands special study. From the point of view of the general work of the machine it can be said in general that this effort is connected with the emotional life, that it is a special kind of influence over one’s emotions. But what this kind of influence really is, and how it has to be produced, can be explained only in connection with a general description of the WORK OF THE HUMAN factory or the human machine. Fragments: Nine

“If we now take the WORK OF THE HUMAN factory as a whole, we shall be able to see at the moments when the production of fine substances is arrested by what means we can increase the productivity of the factory. We see that, under ordinary conditions and working with one mechanical ‘shock’ the factory produces a very small quantity of the fine substances, in fact only si 12. Working with one mechanical and one conscious ‘shock’ the factory now produces a much greater quantity of the fine substances. Working with two conscious ‘shocks’ the factory will produce a quantity of the fine substances such as, in the course of time, will completely change the character of the factory itself. Fragments: Nine

“The study of the WORK OF THE HUMAN organism as a chemical factory shows us three stages in the evolution of the human machine. Fragments: Nine

“The first stage refers to the WORK OF THE HUMAN organism as it has been created by nature, that is to say, to the life and functions of man number one, number two, and number three. The first octave, that is, the octave of food, develops in a normal way to mi 192. At this point it automatically receives a ‘shock’ from the beginning of the second octave, and its development goes on consecutively to si 12. The second octave, that is, the air octave, begins with do 192 and develops to mi 48 where it stops. The third octave, that is, the octave of impressions, begins with do 48 and stops there. Thus seven notes of the first octave, three notes of the second, and one note of the third octave represent a complete picture of the work of the ‘human factory’ in its first or natural stage. Nature has provided only one ‘shock,’ that is, the ‘shock’ received from the entrance of the second octave which helps mi of the first octave to pass to fa. But nature did not foresee and did not provide for the second ‘shock,’ that is, the ‘shock’ that would help the development of the third octave and thereby enable mi of the second octave to pass to fa. A man must create this ‘shock’ by his own personal efforts if he desires to increase the output of the fine hydrogens in his organism. Fragments: Nine

“The second stage refers to the WORK OF THE HUMAN organism when a man creates a conscious volitional ‘shock’ at the point do 48. In the first place this volitional ‘shock’ is transmitted to the second octave which develops as far as sol 12, or even further up to la 6 and so on, if the work of the organism is sufficiently intense. The same ‘shock’ also enables the third octave to develop, that is, the octave of impressions which in this event reaches mi 12. Thus in the second stage of the WORK OF THE HUMAN organism, we see the full development of the second octave and three notes of the third octave. The first octave has stopped at the note si 12, the third at the note mi 12. Neither of these octaves can proceed any further without a fresh ‘shock.’ The nature of this second ‘shock’ cannot be so easily described as the nature of the first volitional ‘shock’ at do 48. In order to understand the nature of this ‘shock’ it is necessary to understand the meaning of si 12 and mi 12. Fragments: Nine

“The third stage in the WORK OF THE HUMAN organism begins when man creates in himself a conscious second volitional ‘shock’ at the point mi 12, when the transformation or transmutation of these ‘hydrogens’ into higher ‘hydrogens’ begins in him. The second stage and the beginning of the third stage refer to the life and functions of man number four. A fairly considerable period of. transmutation and crystallization is needed for the transition of man number four to the level of man number five. Fragments: Nine

“When the ‘table of hydrogens’ has been sufficiently understood, it shows immediately many new features in the WORK OF THE HUMAN machine, establishing clearly before anything else the reasons for the differences between the centers and their respective functions. Fragments: Nine

“In order to understand the WORK OF THE HUMAN machine and its possibilities, one must know that, apart from these three centers and those connected with them, we have two more centers, fully developed and properly functioning, but they are not connected with our usual life nor with the three centers in which we are aware of ourselves. Fragments: Nine

“If we consider the WORK OF THE HUMAN machine from the point of view of the ‘hydrogens’ which work the centers, we shall see why the higher centers cannot be connected with the lower ones. Fragments: Nine
