大乘義章 14.55

14.55

次辨所為。所為有四：一為厭有為故修諸行、二為求菩提滿足佛德故修諸行、三為益眾生欲於現在及未來世救度眾生故修諸行、四為求實際為證法如故修諸行。故彼經言「欲知清淨平等法故，修行精進。」理實諸行皆具此四，但經文中有說不說，隱顯故爾。四中前三為求世法，後一求理。所為如是（此三門竟）。

Next, the purpose is distinguished. The purposes are four: first, practicing the various practices to be weary of the conditioned; second, practicing the various practices to seek bodhi and fulfill the Buddha-virtues; third, practicing the various practices to benefit sentient beings, wishing to rescue and deliver sentient beings in the present and future eras; fourth, practicing the various practices to seek the bhūtakoṭi and to realize the tathatā of dharmas. Therefore, that sutra says: "Because one wishes to know the pure and equal dharma, one cultivates vigor." In truth, all practices possess these four, but in the sutra texts some are stated and some are not, merely because of being concealed or revealed. Among the four, the first three are for seeking conventional dharmas; the last one is for seeking the principle. The purpose is like this (this concludes the third gate).
