4.105

謂住下。法合也。住不住中皆有福故，謂近感十王住中福，遠招菩提不住福。又近得色身住中福，遠得法身不住福。空雖無相非謂無空，福雖不住非謂無福，二者寬廣即橫遍十方，高即竪窮三際，大即通該橫竪，如上之義法喻皆大。

Regarding "meaning abiding, etc.": this is the application to the dharma. Because merit exists within both abiding and non-abiding: proximate, it evokes the abiding merit of the ten kings; ultimate, it brings about the non-abiding merit of bodhi. Furthermore, proximately it obtains the abiding merit of the physical form body; ultimately it obtains the non-abiding merit of the dharmakāya. Although space has no marks, it does not mean there is no space; although merit does not abide, it does not mean there is no merit. Second, its breadth and vastness means it horizontally pervades the ten directions; its height vertically exhausts the three times; its greatness encompasses both horizontal and vertical. According to the above meaning, both dharma and metaphor are great.
