淨名經集解關中疏 1.144

1.144

以斯妙法濟群生。一受不退常寂然。度老病死大醫王。當禮法海德無邊　此三明得益。明斷見修惑得涅槃益也。肇曰。九十六種道上者。亦能斷結生無色界天。但其道不真要還墜三途。佛以四諦妙法濟三乘。眾生無有。既受還墜生死者。故曰。一受不退。永畢無為故常寂然也。又生老病死患之重者。濟以法藥故為醫王之長也。此則法輪淵曠難測。法海流潤無涯德無邊也。

"With this wonderful Dharma he delivered the multitudes of beings; / Once received, they never retrogress and are ever tranquil. / Delivering from old age, sickness, and death, the Great Physician King, / One should pay homage to the Dharma ocean of boundless virtue." These three [lines] clarify the gaining of benefit; they clarify the benefit of severing the defilements of views and cultivation and attaining nirvāṇa. Sengzhao says: "Among the ninety-six paths, the superior ones can also sever the fetters and be born into the formless realm heavens. Yet their path is not genuine; inevitably they fall back into the three evil paths. The Buddha delivers the sentient beings of the three vehicles with the wonderful Dharma of the four truths; none of those who have already received it fall back into birth and death. Therefore it says, 'Once received, they never retrogress.' Because they forever complete the unconditioned, they are 'ever tranquil.' Furthermore, birth, old age, sickness, and death are the gravest of afflictions; he delivers them with the medicine of the Dharma, and therefore he is the foremost of physician kings. Thus the Dharma wheel is unfathomably vast, and the Dharma ocean flows with boundless nourishment, its virtue limitless."
