10.415

世法處苦，有九中，前四是八世法中四也，即違緣合故苦。此中不論利等四者，以是若欣非苦相故，後五即愛法離故生苦。

Suffering in worldly phenomena has nine types; the first four are four of the eight worldly phenomena, which are suffering due to the convergence of adverse conditions. Here, the four such as gain are not discussed because they are delightful and not aspects of suffering; the latter five are suffering arising from separation from beloved phenomena.
