大乘百法明門論開宗義決 1.212

1.212

俱與前二容五相應者。前二謂是睡眠惡作。尋相應時無伺相應。伺相應時無尋俱起。為顯是義故置容言。

"Both admit of association with the former two and with the five [feelings]": the 'former two' refers to sleep and remorse. When there is association with investigation, there is no association with analysis; when there is association with analysis, there is no co-arising with investigation. To reveal this meaning, the word 'admit' is used.
