rūpa (English spelling) rupa

Japanese: rūpa（英語表記）rupa

…The five elements that make up the living being, the sentient being, are form, feeling, thought, action, and consciousness. Of these, form (rūpa) includes the five sense organs that make up the body (the five roots), the five objects of those sense organs (the five realms), and the latent residual energy of action (unmanifest form). Feeling (bhedana) refers to the three sensory functions of pain, pleasure, and non-pain and non-pleasure. …
