言順清淨作意，唯攝樂一分所攝者，景師云：前解順清淨作意者，謂由此故修六隨念或復思惟隨一妙事，彼攝樂作意中具有四道，順清淨作意但攝一分勝進道，修六隨念等道理亦合攝彼觀察作意，以同是勝道故以易知故不說，亦可修六隨念或隨緣一妙事非是斷惑，四道所攝故，唯是彼攝樂作意一分，以非勝進道故，不攝彼了相勝解觀察作意，故知攝樂作意通攝四道及非四道。

Regarding "the mental application conforming to purification is included in only a part of delight": Master Jing says: The earlier explanation of the mental application conforming to purification was that by means of it one cultivates the six recollections or reflects upon any exquisite matter. In that mental application of delight, the four paths are fully present, but the mental application conforming to purification includes only a part of the superior path of progress. In principle, cultivating the six recollections and so forth should also include that examination mental application, because it is identically a superior path; yet because it is easy to understand, it is not mentioned. Alternatively, cultivating the six recollections or taking any exquisite matter as an object is not the abandonment of afflictions; it is included in the four paths and is therefore only a part of that mental application of delight. Because it is not the superior path of progress, it does not include those mental applications of apprehension of marks, resolute engagement, and examination; hence one knows that the mental application of delight applies across the four paths and what is not the four paths.
