This discourse was taught by the Blessed One, taught by the Arahant, the fully enlightened Supreme Buddha. This is as I heard,
“Monks, a monk should meditate reducing sleep, live mindfully, with wise awareness, with a still mind, and with a rapturous mind. At proper occasions, he should contemplate with insight the wholesome qualities called thirty-seven enlightenment factors.
For a monk who meditates reducing sleep, lives mindfully and with wise awareness, with a still and rapturous mind, and at proper occasions contemplates with insight the wholesome qualities called thirty-seven enlightenment factors, one of two fruits is to be expected: liberation here, in this life or if there being some residual defilements, the fruit of non-returning.”
This is the meaning of what the Blessed One said. So, with regard to this, it was said:
Those who meditate reducing sleep, listen to this! Those who are sleeping, wake up!
Wakefulness is better than sleep. For wakeful meditators, there is no fear.
Whoever meditates reducing sleep gains a still and rapturous mind and lives mindfully with wise awareness. At the proper occasions, he can contemplate with insight on the wholesome qualities called the thirty-seven enlightenment factors. With a unified mind he will destroy the darkness of ignorance.
Therefore, associate with a wakeful meditator. The ardent, intelligent, and meditative monk, having cut the fetters of rebirth and aging, realizes supreme Enlightenment here, in this very life.
This, too, is the meaning of what was said by the Blessed One. This is exactly as I heard.
