瑜伽論記 10.464

10.464

言無間修作，殷重修作者，舊論無此。如三摩呬多地說：無間作意者，謂一切時無間無斷相續而轉，殷重作意者，謂不慢緩加行方便。

Regarding the words "uninterrupted practice and earnest practice": the older treatise does not have this. As stated in the Samāhitā Bhūmiḥ: "Uninterrupted attention means continuous and unbroken progression at all times; earnest attention means unrelaxed preparatory application and skillful means."
