大方廣佛華嚴經隨疏演義鈔 28.41

28.41

疏「化滿塵方用周三際」者，辯得用橫竪深廣也。謂十方微塵剎土，皆是文殊化處。故《菩薩處胎經》云「我身如微塵，今在他國土，三十二相明，在在無不現。」餘如眾海雲集中引。又《般泥洹經》云「住首楞嚴三昧，以三昧力，於十方國或現初生出家滅度入般涅槃分布舍利饒益眾生。」又《寶藏陀羅尼經》廣說，至下〈菩薩住處品〉當更明之。即今文中，一切處一時說偈，即橫周法界。

Regarding the commentary's statement, "His transformations fill lands [countless as] dust motes, his functions encompass the three periods of time": this explains that the functions [of Mañjuśrī] are horizontally and vertically deep and vast. That is to say, the dust-mote kṣetras in the ten directions are all places where Mañjuśrī manifests transformations. Hence the Bodhisattva-garbhastha-sūtra says: "My body is like fine dust motes; now in other lands, with the thirty-two marks radiant, there is nowhere I do not manifest." The rest is as quoted in [the section on] "The Gathering of the Ocean-like Assembly." Furthermore, the Mahāparinirvāṇa-sūtra says: "Abiding in the Śūraṅgamasamādhi, through the power of this samādhi, in the lands of the ten directions he may manifest initial birth, leaving home, parinirvāṇa, entering parinirvāṇa, and distributing relics to benefit sentient beings." Furthermore, it is extensively expounded in the Ratnakaraṇḍa-dhāraṇī-sūtra, which will be further clarified below in the chapter on "Abodes of the Bodhisattvas." In the present text itself, his uttering verses everywhere at the same time is precisely his horizontally encompassing the dharmadhātu.
