Vasubandhu's Commentary on the Lotus Sutra, p 134In regard to “repudiating [the Small Vehicle],” it says in the Lotus Sutra, “O Śāriputra! In all the worlds of the ten directions there are no two vehicles, let alone three.” “There are no two vehicles” means there is no nirvana attained through the two vehicles. There is only the great enlightenment realized by the tathāgatas. To completely perfect all wisdom is called the great nirvana. It is not the case that the disciples and self-enlightened buddhas [are able to attain] nirvana since there is only the single buddha vehicle.
