14.199

重辨十對中，云有三品。一、未發趣定品，謂欲界未求定人；二、雖已發趣未得定品，即求定未得人；三者、已得定人。此復二種：一、不清淨，謂伏惑得未至定；二、極清淨，謂得根本定。

In the re-examination of the ten pairs, it says there are three grades: first, the grade of those who have not yet set out toward meditative absorption, referring to persons in the Desire Realm who have not yet sought meditative absorption; second, the grade of those who, although having set out, have not attained meditative absorption, that is, persons who seek meditative absorption but have not attained it; third, persons who have already attained meditative absorption. This latter comprises two kinds: first, impure, referring to having suppressed afflictions and attained the threshold absorption; second, utterly pure, referring to having attained the root absorption.
