29.8

"[Appreciative] joy [relies on] the first two dhyānas; the remaining [three rely on] six, or five, or ten" explains the levels on which they rely. The immeasurable of appreciative joy is established relying solely on the first and second dhyānas. "The remaining six" means that the remaining three immeasurables rely on six levels: the four dhyānas, the threshold (anāgamya), and the intermediate [dhyāna]. "Or five": some masters say they rely only on five levels, excluding the threshold level; they state that cultivating the immeasurables is a relaxed state and that only those who are already detached from desire can cultivate them, hence the threshold is excluded. Others wish to maintain that these four immeasurables rely universally on ten levels: the desire realm, the four fundamental dhyānas, the preliminary stages (sāmantaka) of the four dhyānas, and the intermediate [dhyāna]. The intention here is that both the fundamental and preparatory stages of concentrated and non-concentrated levels are subsumed under the immeasurables; hence they are common to ten levels.
