7.521

前中，或無罪欲樂等者，謂欲界無罪欲樂。初二定地無罪有喜樂，第三定地無罪離喜之樂也。

In the former part, regarding "or faultless pleasures of desire, and so forth": this refers to the faultless pleasures of desire in the desire realm. The stages of the first and second dhyānas have faultless joy and pleasure; the stage of the third dhyāna has faultless pleasure detached from joy.
