6.37

Regarding "of the same stage": it does not serve as a cause for defiled phenomena of different stages. The treatise says: "Because these are common causes for defiled phenomena, they are established separately outside the similar cause; and because they are also causes for defiled phenomena of other categories. By the force of these, defiled phenomena of other categories and their retinues also arise and grow." The explanation says: Taking the fruits of the five categories as a universal cause is called a common cause. As for the similar cause, it is only the fruit of its own category, not a common cause. "Retinues" refers to phenomena associated with and co-existent with the afflictions.
