俱舍論疏 28.8

28.8

論「四各有二至五蘊為性」，分四靜慮各有二種，謂生及定。生者十七天。定即善等持，即名心一境性，并五蘊也。

The Śāstra states: "Each of the four has two... taking the five aggregates as their nature." It divides the four dhyānas into two kinds each: namely, rebirth and meditative absorption. Rebirth refers to the seventeen heavens. Meditative absorption is wholesome concentration (samādhi), which is named one-pointedness of mind, together with the five aggregates.
