法華義疏 3.293

3.293

Regarding 'All that they do is constantly for the sake of one matter': above it was explained that expounding the one principle is for the sake of teaching the one person, which is based on the karma of speech. Now it is explained that 'all that they do' refers to the four postures of movement and stillness as well as all actions of the three karmas, which are all to reveal the one principle and entirely to teach the one person. Regarding 'The Tathāgata expounds the Dharma for sentient beings solely by means of the one Buddha vehicle, and there are no other vehicles, whether two or three': the reason this passage occurs is to explain and consummate the meaning of the preceding three sentences. Because the principle is uniquely one and the principle is without three, the buddhas appear in the world solely for the sake of one matter and solely to teach the one person, up to all that they do being entirely to reveal the one matter. This passage has two clauses: the first clause explains that the principle is uniquely one, and therefore the buddhas rely on the one principle and preach only the one vehicle; hence it is said, 'solely by means of the one Buddha vehicle expounds the Dharma for sentient beings.' As for 'there are no other vehicles, whether two or three,' above it was explained that the principle has solely the one Buddha vehicle; now it is explained that the principle has no other vehicles. The 'other vehicles' are the pratyekabuddha and śrāvaka vehicles. The pratyekabuddha vehicle is the second, and the śrāvaka vehicle is the third; hence it is said that there are no other vehicles, whether two or three.
