仁王護國般若波羅蜜多經疏 1.11

1.11

四明次第者，菩提涅槃是所求證，須修萬行時歷僧祇，從淺至深次第悟證。〈奉持品〉云「云何諸善男子於此經中明了覺解為人演說？佛言：大王！汝今諦聽。從習忍至金剛定，如法修行十三觀門，皆為法師依持建立。故十三門廣明修斷，一德不備無由歸源，勿謂一門致少功力便能圓證無上菩提。」具明修斷，故說此經。

Fourth, clarifying the stages: bodhi and nirvāṇa are that which is sought and realized; one must cultivate myriad practices, passing through asaṃkhyeya kalpas, gradually awakening and realizing from shallow to deep. The 'Chapter on Receiving and Holding' states: 'How do good sons clearly understand and expound for others in regard to this scripture? The Buddha said: "Great King! Listen attentively now. From the kṣānti of practice up to the vajra-like samādhi, practicing the thirteen contemplation portals in accordance with the Dharma, all serve as the support and establishment for Dharma masters."' Therefore, the thirteen portals extensively clarify cultivation and eradication; if a single virtue is lacking, there is no way to return to the source. Do not think that applying little effort in a single portal will allow one to fully realize anuttarasamyaksaṃbodhi. Fully clarifying cultivation and eradication—for this reason, this scripture was spoken.
