相應部51相應12經/大果經(神足相應/大篇/修多羅)(莊春江譯)
「
比丘們！有這些
四神足，已
修習、已
多作，有大果、
大效益。
比丘們！而怎樣四神足已修習、怎樣已多作，有大果、大效益？比丘們！這裡，比丘修習
具備意欲定勤奮之行的神足：像這樣，我的意欲將不是過鬆的、將不是過緊的、將不是向內收斂的、將不是向外散亂的，以及住於
前後有感知的：後如前那樣地，前如後那樣地；上如下那樣地，下如上那樣地；在夜間如在白天那樣地，在白天如在夜間那樣地。像這樣，以打開的、無覆蓋的心，修習有光輝的心。
活力定……（中略）心定……（中略）修習
具備考察定勤奮之行的神足：像這樣，我的考察將不是過鬆的、將不是過緊的、將不是向內收斂的、將不是向外散亂的，以及住於前後有感知的：後如前那樣地，前如後那樣地；上如下那樣地，下如上那樣地；在夜間如在白天那樣地，在白天如在夜間那樣地。像這樣，以打開的、無覆蓋的心，修習有光輝的心。當四神足這麼已修習、這麼已多作，有大果、大效益。
比丘們！這樣，在四神足已修習、這樣已多作時，比丘體驗各種神通種類：是一個後變成多個，又，是多個後變成一個……（中略）以身體行使自在直到梵天世界。……（中略）
比丘們！這樣，在四神足已修習、這樣已多作時，比丘以諸
漏的滅盡，
當生以證智自作證後，
進入後住於無漏
心解脫、
慧解脫。」
