[132] The Blessed One said this: "Bhikkhus, this is the one-way path (ekāyana) for the purification of beings, for the surmounting of sorrow and lamentation, for the disappearance of suffering (dukkha) and grief, for the attainment of the true way (ñāya), for the realization of Nibbāna — namely, the four establishments of mindfulness (satipaṭṭhāna). What four? Here, bhikkhus, a bhikkhu dwells contemplating the body in the body, ardent, clearly comprehending, possessed of mindfulness, having removed covetousness and grief regarding the world. He dwells contemplating feelings (vedanā) in feelings, ardent, clearly comprehending, possessed of mindfulness, having removed covetousness and grief regarding the world. He dwells contemplating the mind (citta) in the mind, ardent, clearly comprehending, possessed of mindfulness, having removed covetousness and grief regarding the world. He dwells contemplating dhammas in dhammas, ardent, clearly comprehending, possessed of mindfulness, having removed covetousness and grief regarding the world."
