noun
realm of existence
Buddhist term for the world of sentient beings, the realm where life exists and transmigrates.
仏教では、有界は苦しみの世界とされる。
In Buddhism, the realm of existence is considered a world of suffering.
Antonym meaning 'realm of non-existence' or 'unconditioned realm', contrasting with the conditioned world of 有界.
From Middle Chinese 有界 (yǒu jiè), literally 'existence realm'. The reading うかい is the standard Sino-Japanese on'yomi; うがい is a less common variant.
