長阿含經 10.p105

10.p105

“If a diligent monk recovers a little from an illness, he thinks, ‘I’ve begun to recover from that illness. It might get worse, which would interrupt my practice. I ought to make effort by sitting in meditation and walking back and forth now.’ He will attain what he has yet to attain, obtain what he has yet to obtain, and realize what he has yet to realize. Thereupon, that monk then immediately makes effort by sitting in meditation and walking. [This is the eighth effort.]
