觀無量壽佛經義疏 2.39

2.39

「『唯願世尊為我廣說無憂惱處，我當往生，不樂閻浮提濁惡世也。』」無憂惱處者，韋提所問。言相通含，據下佛答，即指淨土。娑婆五濁，人間天上皆有憂惱，唯佛淨土依正俱勝，但受諸樂，寧有憂乎？閻浮提，或云剡浮贍部，此翻勝金，從樹為名。以樹半臨海水，水底有金，光色映樹，故以為名。提，或云檀，此翻為洲，即別指南洲也，據令通指娑婆大千。且從近論，令易解耳。或可閻浮於四洲中濁惡最甚，故特標之。二、敘可厭。

"'I only pray that the World-Honoured One will explain for me in detail a place free of sorrow and affliction, where I may attain rebirth; I take no delight in this defiled and evil world of Jambudvīpa.'" A place free of sorrow and affliction is what Vaidehī asked about. The words have a general and inclusive meaning; according to the Buddha's answer below, it directly indicates the Pure Land. In the five turbidities of Sahā, both humans and gods have sorrows and afflictions; only in the Buddha's Pure Land are both the environment and inhabitants supreme, experiencing only happiness—how could there be sorrow? Jambudvīpa, also called Shanbu or Zhanbu, is translated here as "Superior Gold," named after the tree. Because the tree partially overhangs the seawater, and at the bottom of the water there is gold whose lustrous colour reflects upon the tree, it is named after this. Dvīpa, or tan, is translated here as "continent," specifically referring to the southern continent; as used here, it broadly refers to the Sahā trichiliocosm. It is discussed from what is close at hand simply to make it easy to understand. Alternatively, Jambudvīpa is the most severely defiled and evil among the four continents, so it is specially singled out. Second, narrating what is revolting.
