分別起 The afflictions produced from discrimination. Afflictions that are produced subsequent to birth in this world, depending upon the mistaken thoughts that one produces based on incorrect teachings, etc. These afflictions are eliminated in the course of the Path of Seeing 見道, and are contrasted to inherent afflictions (倶生起 and 任運起).
Delusions arising from reasoning and teaching, in contrast with 倶生起 errors that arise naturally among people.
梵語 parikalpasamutthita。即一切煩惱中,由邪教、邪師、邪思惟等所引起者。為「俱生起」之對稱。十根本煩惱中,疑、邪見、見取見、戒禁取見等四者均屬之。分別起易斷,故於見道中,證得生法二空之真如時,得頓斷之。〔成唯識論卷一、卷二、卷六、顯揚聖教論卷六、大乘阿毘達磨雜集論卷四〕(參閱「俱生起」4027)
一切惑障有分別起與俱生起二種,分別起是由邪師邪教邪思惟等後天環境所養成的障惑,俱生起則是與前六識或七識俱起,而為先天所本有的障惑。分別起就是見惑,易斷,俱生起就是思惑,難斷。
分別起===(術語)一切之惑,有分別起與俱生起二種。一切之凡夫,依無始以來之熏習力與身俱生自然而起之諸惑,謂之俱生起。由邪師邪教邪思惟三緣而起之諸惑,謂之分別起。分別起易斷,故於最初頓斷之,即見惑是也,俱生起難斷,故至後漸斷之,即思惑是也。
