Since it is stated to be only the one Buddha vehicle and there is no other vehicle, it causes persons of the two vehicles and so forth to abide in the Buddha vehicle and not abide in other vehicles; hence it says "abiding." Another explanation: the reason why the Buddha's intention spoke of the single vehicle is that he wished to cause all sentient beings to abide in the one Buddha vehicle. As the verse below says: "The Buddha himself abides in the Great Vehicle; / In accordance with the Dharma he has attained, / Adorned with the power of meditation and wisdom, / He uses this to deliver sentient beings." Since the Buddha himself abides in the Great Vehicle, he also causes sentient beings to abide where the Buddha abides; hence it says "causing them to abide." It is also as the *Nirvāṇa [Sūtra]* says: "There is further one practice that is the place of the Tathāgata's practice, called the Great Vehicle's great parinirvāṇa." The Buddha abides in the great nirvāṇa and preaches the Dharma to sentient beings, causing sentient beings to abide.
