5.6

釋曰：無想無想中，心心所法滅者，正釋無想也。上言無想，無想異熟也。下言無想，無想天也。謂無想天中有無想異熟故。論云：「若生無想有情天中，有法能令心、心所滅，名為無想。是實有物能遮未來心、心所法，令暫不起，如堰江河。」（解云：既能滅心，明有實物。依經部宗，無想是假故。此標宗言實物也。）

Explanation: 'In non-conception, cessation of mind and mental factors' directly explains non-conception. The first mention of 'non-conception' is the retributive maturation of non-conception (āsaṃjñika). The second mention of 'non-conception' is the Heaven of Non-conception (Asaṃjñisattva). It means that within the Heaven of Non-conception, there is the retributive maturation of non-conception. The Śāstra states: 'If one is born among the gods of the non-conception sentient beings, there is a dharma that causes the cessation of mind and mental factors, which is called non-conception. It is a really existent entity that can block future mind and mental factors, causing them temporarily not to arise, like damming a river.' (The explanation states: Since it can cause the cessation of mind, it is clear that there is a real entity. Because according to the Sautrāntika school non-conception is nominal, this indicates the school's doctrine that it is a real entity.)
