攝十八不共法者：初「身、口無失」，此二是四種道品正業、語、命也。得供不高，逢毀不下，名「無不定心」。四威儀恒在定，名「無不知已捨」。此二法是四種道品中八種定也。

As for subsuming the eighteen unshared dharmas: First, "the body and speech are free from error"—these two are right action, right speech, and right livelihood among the four kinds of the factors of the path. Not being elated when receiving offerings and not being dejected when encountering disparagement is called "the mind is never undistracted". Constantly being in meditative absorption in the four postures of deportment is called "having no unconsidered equanimity". These two dharmas are the eight kinds of meditative absorption in the four kinds of the factors of the path.
