治禪病祕要法 2.15

2.15

「治之法者，想一金翅鳥，比丘乘上，於大海中遊行無畏，諸龍、羅剎皆悉驚走。鳥取龍食，龍畏怖故，吸水都盡，化為四蛇。金翅鳥王口銜四蛇，比丘坐上求水不得。金翅鳥王眼出火燒蛇，諸蛇驚怖——猶如幻夫所作幻人隱沒不現——入比丘身。從是出定，應服世間斷下之藥，想二火珠，一在胃管溫煖諸脈、一在糞門狀如熱石；想雪山神名欝多伽，身長六丈，白如珂雪，持一香藥名娑呵那伽授與行者。服此藥時，先發無上菩提之心。一服藥已，四百四病終身不動；何況下耶？

"The method of curing it is: visualize a garuḍa on which a bhikṣu rides, roaming fearlessly across the great ocean, while all the nāgas and rākṣasas flee in terror. The bird takes nāgas to eat; out of fear, the nāgas drink up all the water, transforming into four snakes. The garuḍa king holds the four snakes in its beak, and the bhikṣu seated atop it searches for water but cannot find any. Fire issues from the garuḍa king's eyes to burn the snakes, and the snakes are terrified—disappearing like an illusory person created by an illusionist—and enter the bhikṣu's body. Upon emerging from this samādhi, he should take worldly medicine that stops diarrhea. He should visualize two fire jewels: one in the stomach pipe warming all the channels, and one at the anus shaped like a hot stone. He should visualize a deity of the Snow Mountains named Uttaga, whose body is sixty feet tall and white as a shell or snow, holding a fragrant medicine named Sahanaga to bestow upon the practitioner. When taking this medicine, he should first generate the unexcelled mind of bodhi. Having taken this medicine once, the four hundred and four illnesses will never stir for the rest of his life, how much less diarrhea!
