大方廣佛華嚴經隨疏演義鈔 35.41

35.41

疏「又文有四弘可以意得」者，四約四弘也。文中不求五欲等，即顯煩惱無邊誓願斷。但為永滅眾生苦，即眾生無邊誓願度。受持正法修諸智，即法門無盡誓願學。證菩提故，即佛道無上誓願成。故四具矣。

Regarding the Commentary's statement, "Furthermore, the text contains the four vast vows, which can be understood by their meaning": The fourth is in terms of the four vast vows. In the text, "not seeking the five desires" and so forth manifests "afflictions are boundless, I vow to sever them." "Solely to perpetually extinguish the suffering of sentient beings" is "sentient beings are boundless, I vow to liberate them." "Upholding the true Dharma and cultivating all wisdoms" is "Dharma gates are endless, I vow to learn them." "To realize bodhi" is "the Buddha Way is supreme, I vow to accomplish it." Thus, all four are complete.
