大乘義章 12.94

次約受論。受謂苦樂憂喜及捨。此六唯一捨根相應，非是根本禪地攝故。若就諸禪義說，止觀及與還淨或喜相應、或樂相應、或捨相應，在初二禪喜受相應，在三禪中樂受相應，自餘一切捨受相應。六種如是。

These six are associated solely with the faculty of equanimity, because they are not subsumed under the fundamental dhyāna levels. If explained in terms of the meanings of the various dhyānas, stopping, observing, turning, and purifying are variously associated with joy, associated with pleasure, or associated with equanimity: in the first and second dhyānas they are associated with the feeling of joy; in the third dhyāna they are associated with the feeling of pleasure; and in all the rest they are associated with the feeling of equanimity. The six kinds are thus.
