"The two piṭakas" are established in relation to persons. That which, among the three piṭakas, expresses and demonstrates the principles, practices, and fruits of the Mahāyāna is called the Bodhisattva-piṭaka; that which expresses and demonstrates the principles, practices, and fruits of the Hīnayāna is called the Śrāvaka-piṭaka. Therefore the *Mahāyānasūtrālaṅkāra* and the *Mahāyānasaṃgraha* state that due to the difference between the superior and inferior vehicles, there are the Śrāvaka- and Bodhisattva-piṭakas. However, when speaking in terms of persons, persons have three vehicles, which should properly be divided into three piṭakas. Because pratyekabuddhas mostly do not rely on teaching and appear in eras without a buddha—or, if appearing in an era with a buddha, are subsumed under the śrāvakas because their principle and fruit among the four dharmas are identical—for this reason only two kinds of piṭakas are established. If based on the differences in teaching and practice, they may also be expanded into three piṭakas. Thus the *Vimaladattā-paripṛcchā-sūtra* and the *Mahāyānāvatāra-śāstra* state that according to specific meanings they are expanded into three piṭakas. Now, relying on treatises such as the *Alaṅkāra*, according to their common meaning they are combined into two piṭakas. Expanding or combining simply follows either perspective. Furthermore, each of the three piṭakas contains the two piṭakas, and each of the two piṭakas contains the three piṭakas; this twofold and threefold division is made solely in relation to persons and dharmas, as explained in detail in the *Commentary on the Yuanjue jing*. As for being subsumed under the Bodhisattva-piṭaka: because it is Mahāyāna and does not express the Hīnayāna, it is subsumed here.
