華嚴一乘教義分齊章 2.52

2.52

若依圓教，一切時分悉皆不定。何以故？謂諸劫相入故、相即故、該通一切因陀羅等諸世界故，仍各隨處，或一念或無量劫等，不違時法也。餘準而思之。

According to the perfect teaching, all temporal divisions are completely indefinite. Why? Because all kalpas mutually interpenetrate, are mutually identical, and encompass all worlds of Indra's net and so forth; yet in each respective place, whether a single thought-moment or immeasurable kalpas, they do not violate the principle of time. The rest should be contemplated by analogy.
