釋淨土群疑論 6.13

6.13

釋曰：三苦之中唯有一苦，八苦之內亦唯有一苦。既三中無二、八中闕七，唯雖有餘一，不名有苦。如《涅槃經》言「如河少水亦名無水，如食少鹽亦名無鹽。」又如《毘曇》言「大海一渧、須彌一塵，不可說言有山海也。」今此亦爾，縱有少苦，不妨得名為極樂也。又逼迫不安，在身在心名為憂苦，彼土俱無，名為極樂也。

The explanation says: Among the three sufferings there is only one suffering; within the eight sufferings there is also only one suffering. Since of the three, two are absent, and of the eight, seven are lacking, even though one remains, it is not called having suffering. As the Nirvāṇa Sūtra says: "Just as a river with little water is also called having no water, and food with little salt is also called having no salt." And as the Abhidharma states: "A single drop of the great ocean or a single speck of dust of Mount Sumeru cannot be spoken of as having a mountain or an ocean." Now this is likewise so: even if there is slight suffering, it does not prevent it from being named "Utmost Bliss." Furthermore, the agitation and unease pressing upon body and mind is called distress and suffering; that land lacks both, and so it is called "Utmost Bliss."
