18.40

摩偷羅國。有一男子。依優波笈多出家。常好眠睡。有時說法睡眠不聞。教樹下禪亦復睡眠。笈多以神通力。於其四邊化作深坑深一千肘。時比丘睡覺。即便驚怖。時優波笈多復化作路。令其得行。時此比丘。隨路而出。往優波笈多所。優波笈多令其更去。比丘答言。彼有深坑。優波笈多言。此深坑小生死。深坑大所謂生老病死憂悲苦惱。若人不知四諦。則墮其中。比丘聞之。復往樹下加趺而坐。心每思惟恐墮深坑。不復睡眠。以怖畏故思惟精進。除諸煩惱。得阿羅漢果。（出阿育王經第九卷）。

In the kingdom of Mathurā, there was a man who went forth under Upagupta. He was constantly fond of sleeping. Sometimes when [Upagupta] preached the Dharma, he would fall asleep and not hear it; when taught to meditate beneath a tree, he would also fall asleep. Upagupta used his supernatural powers to manifest a deep pit a thousand cubits deep on all four sides of him. When the monk awoke from his sleep, he was at once frightened and terrified. Upagupta then manifested a path to allow him to walk along it. The monk followed the path out and went to Upagupta's presence. Upagupta told him to go back again. The monk answered, saying, 'There is a deep pit there.' Upagupta said, 'This deep pit is small; the deep pit of birth and death is great—namely, birth, old age, sickness, death, sorrow, grief, pain, and anguish. If a person does not know the Four Noble Truths, they will fall into it.' Hearing this, the monk returned to the foot of the tree and sat cross-legged. In his mind he constantly reflected on the fear of falling into the deep pit, and he slept no more. Because of his dread, he reflected and made vigorous efforts, eliminated all afflictions, and attained the fruit of an arhat. (Extracted from the ninth fascicle of the *Aśokarāja-sūtra*.)
