法華玄論 3.14

3.14

答：經題中以引文竟，今當更說。《攝大乘論》引《波若》云「乘有三種，因乘、緣乘、果乘。果乘者，謂常樂我淨。」若爾，《波若》以明四德，云何非常？但人不解經意，謂言無常耳。

Answer: Within the commentary on the sūtra title, the citations have already been made; now I shall explain further. The Mahāyānasaṃgraha cites Prajñā saying: 'Vehicles are of three kinds: the causal vehicle, the conditioning vehicle, and the resultant vehicle. The resultant vehicle refers to permanence, bliss, self, and purity.' If so, Prajñā has already elucidated the four virtues; how could it not be permanent? It is merely that people do not understand the sūtra's intent, and say that it speaks of impermanence.
