法華論疏 1.31

1.31

從首至尾委曲釋者，謂為廣論。今但折其樞要，震領提綱，如脫犀象之牙甬、擿翡翠之毛羽也。勒伽論者，即摩德勒伽，謂解阿毘曇論，此翻為境界。尋斯論旨，能生自他利解，即生解之境界也。

Explaining in detail from beginning to end is called an extensive treatise. Now, only grasping its pivotal essentials, shaking the collar and lifting the net-rope, is like drawing the tusk-points of a rhinoceros or elephant, or plucking the feathers of a kingfisher. As for "mātṛkā treatise," it is the mātṛkā, meaning treatises explaining the Abhidharma; this is translated as "sphere of cognition." Inquiring into the purport of this treatise, it can generate understanding that benefits oneself and others; thus it is the sphere of cognition that generates understanding.
