Geometry
Torus and solid torus
In topology and geometry, a toroidal surface is a ring-shaped skin (S¹ × S¹), while a solid torus is the volume enclosed within the ring and a nested supertoroid is a concentric family of such surfaces.
Also called: supertoroid, two circulations
Limit: The torus is our geometric lens for contemplation and action, not a physical measurement of the cosmos or the human mind.
Why does our tradition take its name from the torus? Because on a toroidal surface, two distinct motions can run simultaneously without colliding: the long way around the ring (the toroidal circulation) and the short way through the center and around the tube (the poloidal circulation).
For us, that geometry is a luminous picture of a whole human life. The inward turn of quiet contemplation, gratitude, and self-correction and the outward reach of work, service, and maintenance are not enemies competing for a straight line. They are the two circulations that keep a life coherent. You can explore this geometry directly in our Two Circulations instrument.
