答無盡中，初四句反責非問。瑣，小也。夫下，正示福田。四輩謂天人龍鬼，即能施之主；三寶即所施之境。猶下，略舉四物以喻無盡；天地生長，喻四輩供養，相續不絕故；山海受用，喻三寶福田，出納無窮故。

In answering about inexhaustibility, the first four sentences turn back to reproach the improper question. "Trifling" (瑣) means small. From "now" (夫) onward, it directly points out the field of merit. The "four classes" refer to devas, humans, nāgas, and ghosts, who are the donors capable of giving; the Triratna is the object of giving. From "like" onward, four things are briefly cited to illustrate inexhaustibility: the growth of heaven and earth illustrates the offerings of the four classes continuing without break; the utility of mountains and seas illustrates the Triratna's field of merit, receiving and disbursing without limit.
