瑜伽論記 4.7

4.7

此卷下云：非於欲界心一境性，由此定等，無悔、歡喜、安樂所引故，即以三義解等引：一、等能引；二、引平等；三、平等方便所引發故，能引所引俱平等也。

Later in this fascicle it says: 'It is not one-pointedness of mind in the desire realm, because this concentration and so forth are induced by lack of regret, joy, and bliss.' Thus equipoise is explained by three meanings: first, equally able to induce; second, inducing equanimity; third, induced by the expedient of equanimity; both the inducer and the induced are equal.
