Substance - the second duality
Out of the first distinction comes the second distinction; the distinction between Soft (Blue: RGB 00F) and Hard (Yellow: RGB FF0). I call this Substance. The Moving and the Moved differ in the other world (Soft) and the space-time continuum (Hard). This is how the four Tetrarchs come about: The Sun (Moving-Soft), Uranus (Moving-Hard), the Moon (Moved-Soft) and Saturn (Moved-Hard).
Thus it is that firmness and strength are the concomitants of death; softness and weakness, the concomitants of life.
