俱舍論疏 27.172

27.172

論「諸從靜慮至還從門出」，述出入心也。「故此從二」者，謂從靜慮定及化心生。「能生二」者，謂能生化及淨定。

On the Śāstra's statement: "All those [who emerge] from a dhyāna ... exit again through the door": This explains the entering and emerging minds. "Therefore it arises from two" means that it arises from the dhyāna concentration and from the conjuring mind. "Capable of producing two" means capable of producing conjuration and pure concentration.
