Systole and diastole are the lower and upper limits of the properties and attributes of [[Things]], [[Beings]], and various aspects of the [[Vast]], including [[space]], [[time]], and [[matter]]. The sole exception is the [[Entities]], which are absolute and unchangeable.

Systole and diastole are among the qualities revealed when an intangible such as space or time is [[iconized]] as the [[Six Orbits of Space]] or the [[Six Orbits of Time]]. Each Orbit possesses its own systole and diastole, and the relationships between the Orbits are mediated through them. In this way are otherwise hidden qualities of these intangibles made apparent and subject to study for the purpose of the [[Work]] and [[Apotheosis]].
