約圓義敘教源
An Account of the Origin of the Teachings in Terms of the Perfect Teaching
(吾祖深體佛意。立一圓教。融會空有。受隨行相。文義廣在戒體戒行門中。餘門亦略明之。則知一家宗旨。唯在於圓)。
(Our patriarch deeply grasped the Buddha's intent and established the Perfect Teaching, which harmonizes Emptiness and Existence. The acceptance, transmission, practice, and characteristics are explained at length in the sections on the essence and practice of the Precepts; other sections also touch on them briefly. From this one knows that the core principle of this school lies solely in the Perfect Teaching.)
羯磨經序云。原夫大雄御宇。意唯拯拔一人。大教膺期。指歸為顯一理。但由群生著欲。欲本所謂我心故能隨其所懷。開示止心之法。然則心為生故之本。滅欲必止心源。止心由乎明慧。慧起假於定發。發定之功。非戒不弘。是故特須尊重於戒。故經云。戒為無上菩提本。應當具足持淨戒。
The preface to the Karma Sutra says: Originally, when the Great Hero governed the world, his sole intent was to rescue each individual being. When the great teaching met its destined time, its ultimate aim was to reveal the single principle. But because sentient beings are attached to desires—and the root of desire is what we call the mind—the Buddha could, in accordance with what each held dear, reveal the Dharma for stilling the mind. Thus the mind is the root from which birth arises; to end desire, one must still the source of the mind. Stilling the mind comes about through clear wisdom. Wisdom arises and depends on the arising of concentration. The power that brings concentration forth cannot be upheld without the Precepts. Therefore one must especially revere and honor the Precepts. Hence the sutra says: "The Precepts are the root of unsurpassed Enlightenment; one should fully uphold the pure Precepts."
