The character for “RA” is composed of the lower semicircle, representing the latent realm, and a small circle positioned at the same points as “MI” (3), “U,” and “CHI.”
“RA” embodies the core intention of something in the phenomenal world (MI) “appearing” or “acting” continuously (CHI) from the boundary or interface (U) between the latent and phenomenal realms.
This symbolizes the fundamental process of creation and action in the universe: the invisible energy of the latent realm traversing the boundaries of space and time to manifest as concrete forms and to continuously exert influence. “RA” can be described as a sound that represents the dynamic aspect of hidden powers becoming manifest and continuously impacting the phenomenal world.
