四分律行事鈔資持記 1.173

1.173

三中，初舉喻。地有二義：一能生，二能持。兩引《遺教》，止得初義。上云諸善，通漏無漏及動不動。下云定慧須約聖道，唯在無漏及不動耳。又下，次引律文，雙示二義。即本律〈說戒揵度〉中文。而言經者，名通三藏，皆佛語故。（舊云：《善生經》者，檢彼無文。）先引文。即下，喻合。經云行根，即能生故。上三約喻，則初師、二足、三地。合法者，初是軌物，二即攝行，三能生功德。

In the third part, the metaphor is first raised. The earth has two meanings: first, able to produce; second, able to support. The two citations from the Bequeathed Teaching attain only the first meaning. Above, 'all good' applies generally to the contaminated and uncontaminated, and the movable and immovable. Below, 'concentration and wisdom' must be applied to the noble path, residing solely in the uncontaminated and immovable. 'Further...' and following next cites the vinaya text to simultaneously show both meanings. This is text from the 'Chapter on the Poṣadha' of our own vinaya. As for calling it a sūtra, the designation extends across the Tripiṭaka because all are the Buddha's words. (Anciently it was said to be the Sujāta-sūtra, but upon inspecting that text there is no such passage.) First the text is cited. 'Namely...' and following matches the metaphor. The sūtra says 'root of practice', which means able to produce. The above three are categorized by metaphor: first, the teacher; second, the feet; third, the earth. Matching them to the Dharma: the first is guiding beings, the second is gathering practices, and the third is being able to produce merit.
