Thus have I heard.

The Bhagava was at one time residing at the market-town called Kammasadhamma in the Kuru country. There the Bhagava addressed the bhikkhus saying “O, Bhikkhus”, and they replied to him, “ Bhadante,”.

Then the Bhagava said:

Bhikkhus, this is the one and the only way for the purification of beings, for overcoming sorrow and lamentation, for the cessation of physical and mental pain , for attainment of the Noble Paths and for the realization of Nibbana . That only way is the four satipatthanas.

What are these four?

Here, a bhikkhu dwells perceiving again and again the body ( kaya ) as just the body, not mine, not I, not self, but just a phenomenon, with diligence, clear understanding , and mindfulness, thus keeping away covetousness and mental pain in the world;

he dwells perceiving again and again feelings (vedana) as just feelings, not mine, not I, not self but just as phenomena, with diligence, clear understanding, and mindfulness, thus keeping away covetousness and mental pain in the world;

he dwells perceiving again and again the mind as just the mind, not mine, not I, not self but just a phenomenon, with diligence, clear understanding, and mindfulness, thus keeping away covetousness and mental pain in the world;

he dwells perceiving again and again dhammas as just dhammas, not mine, not I, not self but just as phenomena, with diligence, clear understanding, and mindfulness, thus keeping away covetousness and mental pain in the world.
