3.39

[Regarding] the Treatise stating: "Furthermore, because all unconditioned [phenomena] are admitted to have neither causes nor effects," etc.: The old Kośa stated that unconditioned [phenomena] are not causes and effects. This mistranslated the character "lacking" (無) as "not" (非). If one says "not", that means they are not among the six causes and five effects. Yet the other school themselves admit that among the six causes, they serve as the efficient cause (kāraṇahetu), and among the five effects, they are the fruit of disjunction (visaṃyogaphala), etc. Here, saying they "have neither cause nor effect" means that although they serve as efficient causes, they lack the function of grasping and yielding effects; because they have no efficacy to cause an effect to arise, they are said to be "without effects." Although unconditioned cessation through deliberation (pratisaṃkhyā-nirodha) is the fruit of disjunction, etc., it does not arise from a cause; hence it is said to be "without cause." Not obstructing the arising of others, it serves as an efficient cause; attained through separation from bondage, cessation through deliberation is disjunction. The other two [unconditioned phenomena] are of the nature of predominance, and both extend to virile action (puruṣakāra). What the Mahāyāna states is explained in the Shunyao.
