俱舍論頌疏論本 20.54

20.54

釋曰：由三因緣煩惱現起：一、由未斷隨眠，即惑因也。二、隨應境現，隨應者，隨其所應也，如順境生貪、違境生瞋等，此惑境界也。三、由非理作意，即起惑加行也。由上三因，煩惱現起。

The commentary explains: Afflictions arise in the present due to three causes and conditions: First, due to unabandoned latent defilements (anuśaya), which are the cause of the afflictions. Second, through the presence of corresponding objects; "corresponding" means in accordance with what is appropriate, as when greed arises toward an agreeable object, or hatred arises toward a disagreeable object, and so forth; this is the objective realm of the afflictions. Third, due to improper mental application (ayoniśo-manaskāra), which is the preparatory effort that arouses the afflictions. By means of these three causes, afflictions arise in the present.
