成唯識論演祕 1.90

Briefly, there are two interpretations: One says: The saṃbhogakāya and nirmāṇakāya are called the Sugata, and "substance" applies to two meanings: if the Sugata is identical to the substance, the substance belongs to the saṃbhogakāya and nirmāṇakāya; if it is the substance of the Sugata, the substance belongs to the dharmakāya. The Venerable Maitreya inherits the precious throne of the Buddha and is a true son of the Buddha, so he is called born of that substance. The second says: Both the Sugata and the substance are the dharmakāya; the wisdom of Maitreya must take Suchness as its object before it can arise, and since wisdom arises on that basis, it is called born of that. Vasubandhu refers to himself and his fellow students as "we," and their master was Bodhisattva Asaṅga.
