YO : The Fourfold Nature and the Birth of Time

The sound “YO” represents the number “4.” At this “YO” stage, the trinity sphere—which progressively formed from “HI” to “FU” and then “MI”—acquires a crucial property: “Yoshosei” (fourfold nature).

This “Yoshosei” refers to four essential elements: wave-like nature, particle-like nature, expansion, and contraction. Katakamuna teaches that by possessing these four qualities, phenomena are able to maintain balance, exist stably, and govern various activities, forming their fundamental essence.

Crucially, it is only at this “YO” stage that time, as we recognize it in the phenomenal world, comes into being. The entity that was referred to as the trinity sphere at the “MI” stage is now called “Toki-no-Mari” (“Sphere of Time”) at the “YO” stage. This implies that the preceding processes of “HI,” “FU,” and “MI” occurred in dimensions where the concept of time, as we experience it, did not yet exist.
