注維摩詰經 9.62

9.62

什曰：煩惱根本有四，三毒及等分也。二萬一千塵垢屬一病，四病故八萬四千也。總說則八萬四千，別相則無量。今言八萬四千，則攝無量，故為門也。肇曰：三毒、等分此四，煩惱之根也。因一根生二萬一千煩惱，合八萬四千。因八萬四千出無量塵垢，故名門也。

[Kumāra]jīva says: Afflictions fundamentally have four roots: the three poisons and their equal combination. Twenty-one thousand defilements belong to each one illness; as there are four illnesses, there are eighty-four thousand. Stated generally, there are eighty-four thousand; regarding particular characteristics, they are immeasurable. Now by speaking of eighty-four thousand, immeasurable ones are subsumed, and thus they are called 'gates.' [Seng]zhao says: The three poisons and their equal combination—these four are the roots of affliction. Based on one root, twenty-one thousand afflictions arise, making eighty-four thousand in total. Because from the eighty-four thousand immeasurable defilements issue forth, they are called 'gates.'
