6.87

清淨不相應者，謂涅槃定慧勝清淨法體己身無故名不相應。雜染相應過患者，由與雜染體相應便生三種過患，一者生老病苦之根本故，二無暇處，三於一切處生四相所迫諸無常性。

Non-conjunction with purity means that the superior pure dharmas of nirvāṇa, concentration, and wisdom are absent in one's own person, hence it is called non-conjunction. The faults of conjunction with defilement mean that through conjunction with defiled entities, three kinds of faults arise: first, being the root of birth, old age, and sickness; second, the unfree states; third, in all places arising being oppressed by the four characteristics of all impermanent natures.
