成唯識論掌中樞要 1.149

1.149

許無因果故者：大乘之中，無為是離繫果。十因中，觀待、攝受、引發、定異、同事、不相違因。得是觀待、攝受、同事、相違、不相違因，能得增上果。今就他宗，又是同品，亦無過失，定有性故。

Regarding the statement "because accepting that it has neither cause nor effect": in the Mahāyāna, the unconditioned is the fruit of disjunction (visamyoga-phala). Among the ten causes, it is the cause of reliance, receiving, initiating, determining, cooperating, and non-contradicting. Attainment is the cause of reliance, receiving, cooperating, contradicting, and non-contradicting, which can obtain the sovereign fruit (adhipati-phala). Now, adopting the other school's view, it is also a homologous instance (sapakṣa), and there is also no fault, because it is definitively an existent entity.
