Once the Blessed One dwelt at Vesali, in the Great Forest, at the Gabled House. In the evening, after had arisen from his seclusion, he went to the sick room and sat down on a prepared seat. Being seated, he addressed the monks as follows:

"O monks, mindfully and clearly comprehending should a monk spend his time! This is my injunction to you!

[1] "And how, O monks, is a monk mindful? He dwells practicing body-contemplation on the body, ardent, clearly comprehending and mindful, having overcome covetousness and grief concerning the world. He dwells practicing feeling-contemplation on feelings, ardent, clearly comprehending and mindful, having overcome covetousness and grief concerning the world. He dwells practicing mind-contemplation on the mind, having overcome covetousness and grief concerning the world. He dwells practicing mind-object-contemplation on mind-objects, having overcome covetousness and grief concerning the world. So, monks, is a monk mindful.

"And how, O monks, is a monk clearly comprehending? He applies clear comprehension in going forward and going back; in looking straight on and in looking elsewhere; in bending and in stretching (his limbs); in wearing the robes and carrying the alms bowl; in eating, drinking, chewing and savoring; in obeying the calls of nature; in walking, standing sitting, falling asleep waking, speaking and being silent — in all that he applies clear comprehension. So, monks, is a monk clearly comprehending.

"If a monk is thus mindful and clearly comprehending, ardent, earnest and resolute, and a pleasant feeling arises in him, he knows: 'Now a pleasant feeling has arisen in me. It is conditioned, not unconditioned. Conditioned by what? Even by this sense-impression[2] it is conditioned. And this sense-impression, indeed, is impermanent, compounded, dependently arisen. But if this pleasant feeling that has arisen is conditioned by a sense-impression which is impermanent, compounded, and dependently arisen, how could such a pleasant feeling be permanent?'

"In regard to both sense-impression and the pleasant feeling, he dwells contemplating impermanence, dwells contemplating evanescence, dwells contemplating detachment, dwells contemplating cessation, dwells contemplating relinquishment. And in him who thus dwells, the underlying tendency to lust in regard to sense-impressions and pleasant feeling vanishes.

"If a painful feeling arises in him, he knows: 'Now a painful feeling has arisen in me. It is conditioned, not unconditioned. Conditioned by what? Even by this sense-impression it is conditioned. And this sense-impression, indeed, is impermanent, compounded, dependently arisen. But if this painful feeling that has arisen is conditioned by a sense-impression which is impermanent, compounded and dependently arisen, how could such a painful feeling be permanent?'

"In regard to both sense-impression and painful feeling, he dwells contemplating impermanence, dwells contemplating evanescence, dwells contemplating detachment, dwells contemplating cessation, dwells contemplating relinquishment. And in him who thus dwells, the underlying tendency to resistance in regard to sense-impression and painful feeling vanishes.

"If a neutral feeling arises in him, he knows: 'Now a neutral feeling has arisen in me. It is conditioned, not unconditioned. Conditioned by what? Even by this sense-impression it is conditioned. And this sense-impression, indeed, is impermanent, compounded, dependently arisen. But if this neutral feeling that has arisen is conditioned by a sense-impression, which is impermanent, compounded and dependently arisen, how could such a neutral feeling be permanent?'

"In regard to both sense-impression and neutral feeling, he dwells contemplating impermanence, dwells contemplating evanescence, dwells contemplating detachment, dwells contemplating cessation, dwells contemplating relinquishment. And in him who thus dwells, the underlying tendency to ignorance in regard to sense-impression and neutral feeling vanishes."
