If we take school-work as an ascending octave, we know that in each octave there are two intervals or gaps, between mi and fa and between si and do. In order to pass through these gaps without changing the character or the line of the work it is necessary to know how to fill them. So if I want to guarantee the direction of the work in a straight line, I must work on three lines simultaneously. If I work only on one line, or on two lines, the direction will change. If I work on three lines, or three octaves, one line will help another to pass the interval by giving the necessary shock. It is very important to understand this. School-work uses many cosmic ideas, and three lines of work is a special arrangement to safeguard the right direction of the work and to make it successful. The first line is work on oneself: self-study, study of the system and trying to change at least the most mechanical manifestations. This is the most important line. The second line is work with other people. One cannot work by oneself; a certain friction, inconvenience and difficulty of working with other people creates the necessary shocks. The third line is work for the school, for the organization. This last line takes on different aspects for different people.
