大毘盧遮那經供養次第法疏 1.35

1.35

「所修一切眾善業」以下，第九迴向方便真言門，頌真言同前。本覺真智外無散，以無散故同迴向，勤苦念誦此真言，歸真本法云迴向。

From "All the wholesome karma cultivated" onward is the ninth, the mantra gate of the upāya of pariṇāmanā; the verses and mantra are the same as before. Outside the true wisdom of original enlightenment there is no dissipation; because there is no dissipation, it is identical to pariṇāmanā. Diligently reciting this mantra and returning to the original reality of the Dharma is called pariṇāmanā.
