法華義疏 5.233

5.233

「財富無量」者，第四、歎巨富，即是大富長者，世之財寶能離苦得樂，法寶亦能離生死苦得大涅槃樂，福慧具足為財富，出用不窮名無量。又眾德圓滿為財富，異於因住稱無量。多有田宅，智斷具足能生物善為田，慈悲覆陰稱之為宅。又養命曰田，安身為宅。法寶亦然，能養物慧命若田，安物法身如宅，能安養者無窮故云多也。

Regarding "his wealth was immeasurable": this fourth [phrase] praises his immense wealth; that is, he is an immensely wealthy elder. Mundane wealth and treasures can bring relief from suffering and attainment of joy; the Dharma-treasure can likewise bring relief from the suffering of birth and death and attainment of the joy of great nirvāṇa. The complete endowment of merit and wisdom is "wealth"; its expending and use being inexhaustible is called "immeasurable." Furthermore, the full perfection of all virtues is "wealth"; differing from an abiding cause is called "immeasurable." "Having many fields and houses": the complete endowment of wisdom and eradication [of defilements], being able to generate the wholesome roots of beings, serves as "fields"; being covered and shaded by benevolence and compassion is called "houses." Furthermore, sustaining life is called "fields"; settling the body is called "houses." The Dharma-treasure is also like this: being able to nourish beings' life of wisdom is like fields; settling beings' dharmakāya is like houses; because what can settle and nourish them is inexhaustible, it is called "many."
