妙法蓮華經玄贊 3.161

3.161

上來所說總別果因以解四種，准下三世佛法之中，不說初開，唯說示、悟、入，故知但應如此說善，示悟別顯二果已周，不假標故，舉此二種攝佛一切有為無為萬德盡故。此〈方便品〉法說一乘唯為上根，由此通辨若因若果菩提涅槃以為一乘。〈譬喻品〉中為中根者但說於悟，牛車菩提智德一乘，由唯迷因智不迷因理、果智理故。〈化城喻品〉為下根者但說於示，寶所涅槃斷德一乘，由迷果理不迷果智，因理智故各隨所宜斷除彼障，令其進入偏說一乘，或為中下互說因果智理二門，影顯令解。唯此一品通明因果覺寂一乘，理義周備，故本論中具解此品，餘品但總釋其大意不異此故，若解此品便解一部矣。然勘下文，牛車在果，即是菩提，下文但明因中之智，三乘乘此至道場故。又理雖然，諸經論中多說涅槃理性智慧以為一乘，一乘本故如《無量義》。

The general and specific fruitions and causes explained above were used to interpret the four kinds. According to the Dharma of the buddhas of the three times below, the initial 'opening' is not mentioned, and only 'showing, awakening, and entering' are spoken of. Therefore we know that only explaining it in this way is good, because 'showing' and 'awakening' separately reveal the two fruitions completely and there is no need to set up [a general opening], for citing these two encompasses all conditioned and unconditioned myriads of virtues of the Buddha. In this 'Expedient Means Chapter', the Dharma expounds the Single Vehicle only for those of superior faculties, and thereby generally discerns bodhi and nirvāṇa, whether as cause or as fruition, as the Single Vehicle. In the 'Parable Chapter', for those of medium faculties, only 'awakening' is spoken of: the ox cart, bodhi, and the virtue of wisdom as the Single Vehicle, because they are deluded only about the cause-wisdom, not about the cause-principle or fruition-wisdom and principle. In the 'Conjured City Parable Chapter', for those of lower faculties, only 'showing' is spoken of: the treasure house, nirvāṇa, and the virtue of abandonment as the Single Vehicle, because they are deluded about the fruition-principle, not about the fruition-wisdom or cause-principle and wisdom; according to what is appropriate, their obscurations are severed, causing them to enter by exclusively speaking of the Single Vehicle. Or for those of medium and lower faculties, the two doors of cause and fruition, wisdom and principle, are alternately spoken of, reflecting each other to cause them to understand. Only this single chapter comprehensively clarifies cause and fruition, awakening and quiescence, as the Single Vehicle, with principle and meaning complete and fully prepared; therefore in the root treatise, this chapter is explained in full, while the remaining chapters only summarize their general meaning as not differing from this; if one understands this chapter, one then understands the entire work. However, examining the text below, the ox cart is in the fruition, which is bodhi; the text below only clarifies the wisdom in the cause, because the three vehicles ride this to reach the place of enlightenment. Moreover, although the principle is thus, in many sūtras and treatises the wisdom of the nature and principle of nirvāṇa is spoken of as the Single Vehicle, for it is the root of the Single Vehicle, as in the Anantanirdeśa-sūtra.
