維摩經玄疏 4.23

4.23

七、明妙覺地者，究竟解脫，無上佛智，故言：「無所斷者，名無上士。」此即是究竟後心，三德不縱不橫，大涅槃也。「大涅槃」，名諸佛法界，豎深橫闊，能用二十五三昧普化眾生；隱顯十番利物，究竟周普。譬如大樹，根若深極，枝條亦大。若實相智慧，窮源盡性，化用之功，則彌滿法界，無方大用，究竟圓極也。故《大智論》云「智度大道佛從來，智度深海佛窮底」也，《大品經》云「過『茶』，無字可說」，《大涅槃經》云「不生不生不可說」也。若作此而辨位者，前三十心來諸地，皆是寂滅真如、平等法界不思議無次位之位也。

Seventh, clarifying the ground of marvelous enlightenment: ultimate liberation, unsurpassed buddha-wisdom; hence it is said: "One who has nothing left to sever is called the unsurpassed person." This is the ultimate final mind, the three virtues neither vertical nor horizontal, the great nirvāṇa. "Great nirvāṇa" is called the dharma-realm of all buddhas, vertically profound and horizontally vast, capable of employing the twenty-five samādhis to universally transform sentient beings; concealing and manifesting in ten turns to benefit beings, ultimately and universally complete. Just as with a great tree, if its roots are exceedingly deep, its branches are also great. When the wisdom of the true mark exhausts the source and penetrates the nature, its efficacy in transformative functioning then fills the dharma-realm; its boundless great functioning is ultimately and perfectly consummate. Hence the Mahāprajñāpāramitopadeśa says: "The great path of the perfection of wisdom is where buddhas come from; the deep ocean of the perfection of wisdom is where buddhas reach the bottom." The Pañcaviṃśatisāhasrikā Sūtra says: "Beyond ḍha, there is no letter that can be spoken." The Mahāparinirvāṇa Sūtra says: "Non-arising and non-arising cannot be spoken." If one demarcates the stages in this way, all the grounds following the previous thirty minds are the stages of no sequence of stages, which are inconceivable, quiescent true suchness and the equanimous dharma-realm.
