Thus have I heard. At one time the Blessed One was living among the Kurus, at Kammasadamma, a market town of the Kuru people. There the Blessed One addressed the bhikkhu thus: "Monks," and they replied to him, "Venerable Sir." The Blessed One spoke as follows:

This is the only way, monks, for the purification of beings, for the overcoming of sorrow and lamentation, for the destruction of suffering and grief, for reaching the right path, for the attainment of Nibbana, namely, the four foundations of mindfulness. What are the four?

Herein (in this teaching) a monk lives contemplating the body in the body,[1] ardent, clearly comprehending and mindful, having overcome, in this world, covetousness and grief; he lives contemplating feelings in feelings, ardent, clearly comprehending and mindful, having overcome, in this world, covetousness and grief; he lives contemplating consciousness in consciousness,[2] ardent, clearly comprehending and mindful, having overcome, in this world, covetousness and grief; he lives contemplating mental objects in mental objects, ardent, clearly comprehending and mindful, having overcome, in this world, covetousness and grief.

I. The Contemplation of the Body

1. Mindfulness of Breathing

And how does a monk live contemplating the body in the body?

Herein, monks, a monk, having gone to the forest, to the foot of a tree or to an empty place, sits down with his legs crossed, keeps his body erect and his mindfulness alert.[3]

Ever mindful he breathes in, mindful he breathes out. Breathing in a long breath, he knows, "I am breathing in a long breath"; breathing out a long breath, he knows, "I am breathing out a long breath"; breathing in a short breath, he knows, "I am breathing in a short breath"; breathing out a short breath, he knows, "I am breathing out a short breath."

"Experiencing the whole (breath-) body, I shall breathe in," thus he trains himself. "Experiencing the whole (breath-) body, I shall breathe out," thus he trains himself. "Calming the activity of the (breath-) body, I shall breathe in," thus he trains himself. "Calming the activity of the (breath-) body, I shall breathe out," thus he trains himself.

Just as a skillful turner or turner's apprentice, making a long turn, knows, "I am making a long turn," or making a short turn, knows, "I am making a short turn," just so the monk, breathing in a long breath, knows, "I am breathing in a long breath"; breathing out a long breath, he knows, "I am breathing out a long breath"; breathing in a short breath, he knows, "I am breathing in a short breath"; breathing out a short breath, he knows, "I am breathing out a short breath." "Experiencing the whole (breath-) body, I shall breathe in," thus he trains himself. "Experiencing the whole (breath-) body, I shall breathe out," thus he trains himself. "Calming the activity of the (breath-) body, I shall breathe in," thus he trains himself. "Calming the activity of the (breath-) body, I shall breathe out," thus he trains himself.

Thus he lives contemplating the body in the body internally, or he lives contemplating the body in the body externally, or he lives contemplating the body in the body internally and externally.[4] He lives contemplating origination factors[5] in the body, or he lives contemplating dissolution factors[6] in the body, or he lives contemplating origination-and-dissolution factors[7] in the body. Or his mindfulness is established with the thought: "The body exists,"[8] to the extent necessary just for knowledge and mindfulness, and he lives detached,[9] and clings to nothing in the world. Thus also, monks, a monk lives contemplating the body in the body.

2. The Postures of the Body

And further, monks, a monk knows, when he is going, "I am going"; he knows, when he is standing, "I am standing"; he knows, when he is sitting, "I am sitting"; he knows, when he is lying down, "I am lying down"; or just as his body is disposed so he knows it.

Thus he lives contemplating the body in the body internally, or he lives contemplating the body in the body externally, or he lives contemplating the body in the body internally and externally. He lives contemplating origination factors in the body, or he lives contemplating dissolution factors in the body, or he lives contemplating origination-and-dissolution factors in the body.[10] Or his mindfulness is established with the thought: "The body exists," to the extent necessary just for knowledge and mindfulness, and he lives detached, and clings to nothing in the world. Thus also, monks, a monk lives contemplating the body in the body.

3. Mindfulness with Clear Comprehension

And further, monks, a monk, in going forward and back, applies clear comprehension; in looking straight on and looking away, he applies clear comprehension; in bending and in stretching, he applies clear comprehension; in wearing robes and carrying the bowl, he applies clear comprehension; in eating, drinking, chewing and savoring, he applies clear comprehension; in walking, in standing, in sitting, in falling asleep, in waking, in speaking and in keeping silence, he applies clear comprehension.

Thus he lives contemplating the body in the body...

4. The Reflection on the Repulsiveness of the Body

And further, monks, a monk reflects on this very body enveloped by the skin and full of manifold impurity, from the soles up, and from the top of the head-hairs down, thinking thus: "There are in this body hair of the head, hair of the body, nails, teeth, skin, flesh, sinews, bones, marrow, kidney, heart, liver, midriff, spleen, lungs, intestines, mesentery, gorge, feces, bile, phlegm, pus, blood, sweat, fat, tears, grease, saliva, nasal mucus, synovial fluid, urine."

Just as if there were a double-mouthed provision bag full of various kinds of grain such as hill paddy, paddy, green gram, cow-peas, sesamum, and husked rice, and a man with sound eyes, having opened that bag, were to take stock of the contents thus: "This is hill paddy, this is paddy, this is green gram, this is cow-pea, this is sesamum, this is husked rice." Just so, monks, a monk reflects on this very body enveloped by the skin and full of manifold impurity, from the soles up, and from the top of the head-hairs down, thinking thus: "There are in this body hair of the head, hair of the body, nails, teeth, skin, flesh, sinews, bones, marrow, kidney, heart, liver, midriff, spleen, lungs, intestines, mesentery, gorge, feces, bile, phlegm, pus, blood, sweat, fat, tears, grease, saliva, nasal mucus, synovial fluid, urine."

Thus he lives contemplating the body in the body...

5. The Reflection on the Material Elements

And further, monks, a monk reflects on this very body, however it be placed or disposed, by way of the material elements: "There are in this body the element of earth, the element of water, the element of fire, the element of wind."[11]

Just as if, monks, a clever cow-butcher or his apprentice, having slaughtered a cow and divided it into portions, should be sitting at the junction of four high roads, in the same way, a monk reflects on this very body, as it is placed or disposed, by way of the material elements: "There are in this body the elements of earth, water, fire, and wind."

Thus he lives contemplating the body in the body...

6. The Nine Cemetery Contemplations

(1) And further, monks, as if a monk sees a body dead one, two, or three days; swollen, blue and festering, thrown in the charnel ground, he then applies this perception to his own body thus: "Verily, also my own body is of the same nature; such it will become and will not escape it."

(7) And further, monks, as if a monk sees a body thrown in the charnel ground, reduced to bleached bones of conchlike color...

(8) And further, monks, as if a monk sees a body thrown in the charnel ground reduced to bones, more than a year-old, lying in a heap...

(9) And further, monks, as if a monk sees a body thrown in the charnel ground, reduced to bones gone rotten and become dust, he then applies this perception to his own body thus: "Verily, also my own body is of the same nature; such it will become and will not escape it."

Thus he lives contemplating the body in the body internally, or he lives contemplating the body in the body externally, or he lives contemplating the body in the body internally and externally. He lives contemplating origination factors in the body, or he lives contemplating dissolution factors in the body, or he lives contemplating origination-and-dissolution factors in the body. Or his mindfulness is established with the thought: "The body exists," to the extent necessary just for knowledge and mindfulness, and he lives detached, and clings to nothing in the world.
