大毘盧遮那經供養次第法疏 2.61

2.61

第三段中，各當隨所安者，從本不生來，今還本不生。後復垂哀赴者，赴為眾生來，後請還度，我不捨去也。若深密釋者，既自作本尊，何時離佛海也。法界本性者，囕字也。明者，真言也。印者，手印也。三印者，入佛法界薩埵也，皆悉圓滿。於明相中入道場坐時，事了也。日中初夜亦復如是。

In the third section, 'each should rest according to their comfort' means coming from ādy-anutpāda, now they return to ādy-anutpāda. 'Afterward, again showing pity and coming' means they came for the sake of sentient beings, and one requests that they later return to liberate them, never abandoning me. If interpreted according to the esoteric meaning: since one has already made oneself the deity, when does one ever separate from the ocean of Buddhas? 'Intrinsic nature of the dharmadhātu' is the syllable RAṂ. 'Vidyā' is mantra. 'Mudrā' is hand seal. 'Three mudrās' means entering the sattva of the Buddha-dharmadhātu; all are fully completed. When entering the bodhimaṇḍa and sitting in the morning light, the matter is finished. Noon and the first watch of the night are also like this.
