"Kuon jitsujo" is the thought in the teachings of Hoke-kyo Sutra (the Lotus Sutra) according to which Buddha was not enlightened at the age of thirty-five but was coming from the eternal past as Buddha (the enlightened one) by Rinne Tensho (the belief that all things are in flux through the endless circle of birth, death, and rebirth, or the circle of transmigration).
久遠実成（くおんじつじょう)とは、法華経の教えにおいて、釈迦は35歳で悟りを開いたのではなく永遠の過去から仏（悟りを開いた者）となって輪廻転生してきているという考え方。
