law of seven
- I went ahead and googled this up.
The law of Seven is a law of vibrations. Just as in modern physics,
this ancient idea considers the world to consist of vibrations, and
this is a general law to help understand this, for practice use.
To increase the rate of vibrations of a material, we need to apply
energy to it. E.g, to raise the temperature, you need to apply heat
to a substance. In popular physics not much attention is given to the
fact that the increase in the rate of vibrations is not always
directy related to the rate of application of energy, i.e. applying
energy at a constant rate does not always give a constant increase in
the rate of vibrations. A very simple example is in heating water
from ice to steam - there are two points, the point when the ice is
at 0 degrees C, but not yet melted, and the point when the water is
at 100 degrees C, but not yet steam. At these two points, one has to
keep applying heat for a longer period of time for the temperature to
Now, the theory is that this pattern will occur for vibrations in any
kind of material, and here we are talking about a wider category of
material than physics usually deals with, for instance, one's own
The points of slowing down in the rate of increase of the rate of
vibrations are called intervals.
Thus a process can be broken into three stages, that before the first
interval, that between the first and second interval, and that after
the second interval, just like the stages ice, water, steam.
We go a step further in this theory, and break a process up into 7
steps, or 8, with the last step in some way considered equivalent to
the first. In Western music, there are 7 notes, DO, RE, ME, FA, SO,
LA, SI, forming an octave. This terminology is used in the work to
refer to any process taken from what would be called Do to Do, the
start and the end.
It is very useful to have an understanding of octaves, as activities
will follow octaves.
