仁王護國般若波羅蜜多經疏 3.401

3.401

解曰：言心心者，前後之心或心心所也。言寂滅者，明證理也。無身心相者，若身若心無所施作，寂不動故。上句明心、下句明相，是二別故。猶如虛空者，喻總明也。如《花嚴》云「離一切心意識分別，無所取著，猶如虛空，入一切法如虛空性，各別明故。」從此第二明不起心。

The commentary states: 'Mind after mind' refers to prior and subsequent minds, or mind and mental factors. 'Quiescent' explains the realization of principle. 'There are no characteristics of body or mind' means that whether body or mind, there is no intentional operation, being quiescent and motionless. The upper line explains mind, and the lower line explains characteristics; these two are distinct. 'Just like empty space' is a simile that explains generally. As the Avataṃsaka says, 'Free from all discrimination of mind, intellect, and consciousness, without anything grasped, just like empty space, entering all dharmas as having the nature of empty space,' which explains them separately. From here, the second part explains not giving rise to mind.
