大毘盧遮那成佛經疏 8.35

8.35

The above word 'womb/treasury' in Sanskrit is garbha, which means the central treasury, the womb-treasury of the central womb, differing in meaning from piṭaka, kośa, and the like. Just as when the bodhisattva was in the heavenly palace and when descending from heaven, there were immeasurable and boundless auspicious events in the worlds, as extensively spoken in the Avataṃsaka and other sūtras. 'Sura' means the heavenly hosts; in order to distinguish them from the devas, they are called asuras. Treatises such as the Lokasthiti call them non-gods. Furthermore, tathāgata is translated as 'thus come' (rulai) and also as 'thus gone' (ruqu), meaning gone from the path of reality to nirvāṇa, never to be reborn; hence it is so named. Using it to explain the time of descending from heaven is convenient for the sense, so the terms are used interchangeably. If Tuṣita Heaven has a bodhisattva bound to one more birth, the seed of Buddhahood in the world will not be cut off. If a person receives the station of consecration in the secret treasury, he may even accomplish right awakening in a single lifetime; hence it says 'identical to that felicity'.
