大般涅槃經集解 20.14

20.14

案僧亮曰：凡夫於中猶尚無疑行道，便易進趣佛果，況聖人乎。釋上義也。敬遺記僧宗曰：疑是解津，既有重倒在心，何容知疑耶？氣力輕便者，謂羸人不堪多蘇。躁動不停、斷常不定，捉放易轉也。慧朗述僧宗曰：謂凡夫聞已即得無復疑也。如羸病者服蘇，氣力得輕便而鮮舉也。寶亮曰：無疑者，結上意也。從「如人服蘇」已下，第三意，總舉得失作譬。此服蘇之譬，明得失有也。謂智者得理必有利益，如病人服蘇得氣力也。下以四大譬失者也。

Sengliang comments: Even ordinary persons have no doubts in this regard when practicing the path, easily advancing toward the Buddha-fruit; how much more so the noble ones! This explains the meaning above. The record of Sengzong by Jingyi states: Doubt is the crossing to understanding; when an intense inversion resides in the mind, how could they know to doubt? 'Bodily strength becomes light and supple' means that a weak person cannot tolerate much clarified butter. Restlessly moving without stop, uncertain between annihilation and permanence, they readily shift between grasping and releasing. Huilang's account of Sengzong states: It means that upon hearing it, ordinary people immediately become free of doubt, just as a weak, sick person takes clarified butter and their physical strength becomes light, agile, and briskly refreshed. Baoliang comments: 'Have no doubt' concludes the preceding thought. From 'like a person taking clarified butter' onward is the third point, generally citing gain and loss to make a simile. This simile of taking clarified butter clarifies the existence of gain and loss. It means that when a wise person attains the principle, there must be benefit, just as a sick person taking clarified butter gains strength. Below, the four great elements are used as a simile for those who incur loss.
