5.5

Calming and contemplation is opened into ten [objects]: first, the aggregates, realms, and sense fields; second, afflictions; third, illnesses; fourth, karmic signs; fifth, demonic affairs; sixth, dhyāna concentrations; seventh, views; eighth, excessive pride; ninth, the two vehicles; tenth, the bodhisattva. These ten realms are all capable of covering and obstructing.
