10.579

泰云：言或於遠離者，阿蘭若處等。或於心一境性者，正修定也。或於清淨諸障者，或依定斷惑也。或於修作意者，依定修七作意也。

Tai says: "The words 'or in seclusion' mean an araṇya and so forth. 'Or in one-pointedness of mind' means correctly cultivating concentration. 'Or in purifying all obstacles' means relying on concentration to sever afflictions. 'Or in cultivating mental engagement' means relying on concentration to cultivate the seven mental engagements."
