法華玄論 4.66

4.66

Answer: The One Vehicle is the orthodox teaching of all Buddhas of the three times, so it is explained in this context. Furthermore, only with such an awakening can one move and transcend; thus it is a vehicle. If one forms a fixed attachment to a single phrase, neither moving nor transcending, how could it be called a vehicle? The Mahāparinirvāṇa-sūtra states: "If there are fixed characteristics, these are characteristics of saṃsāra, characteristics of Māra the King, not characteristics of the Buddhadharma." Therefore, all phenomena have no fixedness and no characteristics.
