1.61

First, as for the Differently Expounded Sūtra: since world-realms of tree-shapes and the like are diverse, the retribution classes of the sentient beings within them are also distinct. When the Tathāgata manifests a body and establishes the teaching there, he establishes distinctive and different teachings according to what is appropriate for them, equal to empty space and the dharmadhātu, which can only be known by the Tathāgata's wisdom; their form and formlessness, speech and speechlessness, and so forth cannot be determined. In the "Rocana Chapter", it broadly clarifies the oceans of world-realms in tree-shapes, river-shapes, Mount Sumeru-shapes, up to the shapes of all sentient beings, and concludes at the end by saying: "All are places where Rocana Buddha constantly turns the wheel of the Dharma." The explanation says: The text only says "constantly turns the wheel of the Dharma" and does not state the demarcation and characteristics of the dharmacakra, because those provisions are different from here, and are thus not revealed. It can be known by analogy that such Dharma teachings are also established in those places, whose divisions and classes are difficult to measure and cannot be described.
