成唯識論述記 1.277

1.277

述曰：自下破餘四蘊。不恒相續，是間斷義。待眾緣者，籍緣起義。量云：心、心所法亦非實我；不恒相續故，待眾緣故；喻如燈聲。此既二因，比量亦二。四蘊非色，體類是同，合為量破。並如色蘊，別破亦得。此破於蘊計為實我，說假我者，亦不遮之。前破心所即行蘊少分，行蘊少分中不相應行。既與心所別，故應別破之。

The Commentary states: From here on, [the text] refutes the remaining four aggregates. 'Not constantly continuous' means having interruptions. 'Depending on multiple conditions' means arising based on conditions. The formal inference (anumāna) is: Mind and mental factors are also not a real self; because they are not constantly continuous, and because they depend on multiple conditions; like a lamp or a sound. Since there are two reasons (hetu) here, there are also two formal inferences. The four aggregates are not matter, and their nature and category are the same, so they are combined into one syllogism for refutation. Or, just like the aggregate of form (rūpa-skandha), they can also be refuted separately. This refutes positing an aggregate as a real self; positing a nominal self is not ruled out here. The previous refutation of mental factors was a small part of the aggregate of conditioning factors (saṃskāra-skandha); among the small part of the saṃskāra-skandha, the non-associated conditioning factors (citta-viprayukta-saṃskāra) are different from mental factors, so they should be refuted separately.
