俱舍論疏 20.156

20.156

論「如是且依至前後無定」，此明起不定也。《正理論》云「諸隨眠起無定次第，可一切後一切生故。」

Regarding the treatise's statement from "This is tentatively based on" to "there is no fixed sequence": This clarifies that their arising is not fixed. The Nyāyānusāra states: "The arising of the various anuśayas has no fixed order, because anything can arise after everything."
