The character for “U” is composed of the upper semicircle representing the Latent World, the vertical line signifying the latent, and a small circle positioned at the location corresponding to the numeral 3 (MI).
The sound “U” embodies the core intention of the “boundary” or “interface of manifestation” where all things are generated in the phenomenal world as the Latent (Kamu) and Phenomenal (Ama) realms superpose. The interface indicated by “U” isn’t a specific, designated place; it exists everywhere in this universe. Naturally, it’s present all around us as well.
“U” symbolizes the dynamic moment of creation and its boundary, where the invisible, fundamental energy takes on concrete form. It suggests the universal process of the cosmos, constantly giving birth to and transforming matter.
