MU: The Expansive Environment
The character for “MU” represents the number “6.” Its elements are composed of the lower semicircle, signifying the Latent World, with a “cross” and a small circle positioned at the bottom left.
The number “6” here represents six directions: left/right, front/back, and up/down. This carries the fundamental core intention of an infinitely expanding “large environment.” Following the processes of HI FU MI YO I (where spacetime emerges) and MA WA RI TE ME KU RU (where phenomena gain form and stability), “MU” symbolizes the vast entirety of the cosmos that encompasses all these, or the “field” where all phenomena unfold.
This suggests Katakamuna‘s cosmology, where the universe we exist in isn’t merely a static space, but a dynamic and inclusive environment that expands infinitely in various directions and accommodates all activities.
