The Noble Eightfold Path
MN 44.11 explains that the eight factors can be incorporated into three “aggregates” of training.
Right speech, right action, and right livelihood make up the aggregate of virtue or moral discipline (sīla);
right effort, right mindfulness, and right concentration make up the aggregate of concentration (samādhi);
and right view and right intention make up the aggregate of understanding or wisdom (paññā).
This threefold sequence in turn serves as the basic outline for the gradual training.
“The three aggregates are not included by the Noble Eightfold Path, friend Visākha, but the Noble Eightfold Path is included by the three aggregates. Right speech, right action, and right livelihood — these states are included in the aggregate of virtue. Right effort, right mindfulness, and right concentration — these states are included in the aggregate of concentration. Right view and right intention — these states are included in the aggregate of wisdom.”
Right view
Knowledge of suffering, knowledge of the origin of suffering, knowledge of the cessation of suffering, knowledge of the way leading to the cessation of suffering: this is called right view.
A.K.A. The Four Noble Truths
Right intention
Intention of renunciation, intention of non–ill will, intention of harmlessness: this is called right intention.
“And how, householders, are there three kinds of righteous mental conduct, conduct in accordance with the Dhamma? Here someone is not covetous; he does not covet the wealth and property of others thus: ‘Oh, may what belongs to another be mine!’ His mind is without ill will, and he has intentions free from hate thus: ‘May these beings be free from enmity, affliction, and anxiety! May they live happily!’ He has right view, undistorted vision, thus: ‘There is what is given and what is offered and what is sacrificed; there is fruit and result of good and bad actions; there is this world and the other world; there is mother and father; there are beings who are reborn spontaneously; there are good and virtuous ascetics and brahmins in the world who have themselves realized by direct knowledge and declare this world and the other world.’ That is how there are three kinds of righteous mental conduct, conduct in accordance with the Dhamma.
Right speech
Abstinence from false speech, abstinence from malicious speech, abstinence from harsh speech, abstinence from idle chatter: this is called right speech.
“And how, householders, are there four kinds of righteous verbal conduct, conduct in accordance with the Dhamma? Here someone, abandoning false speech, abstains from false speech; when summoned to a court, or to a meeting, or to his relatives’ presence, or to his guild, or to the royal family’s presence, and questioned as a witness thus: ‘So, good man, tell what you know,’ not knowing, he says, ‘I do not know,’ or knowing, he says, ‘I know’; not seeing, he says, ‘I do not see,’ or seeing, he says, ‘I see’; he does not in full awareness speak falsehood for his own ends, or for another’s ends, or for some trifling worldly end. Abandoning malicious speech, he abstains from malicious speech; he does not repeat elsewhere what he has heard here in order to divide [those people] from these, nor does he repeat to these people what he has heard elsewhere in order to divide [these people] from those; thus he is one who reunites those who are divided, a promoter of friendships, who enjoys concord, rejoices in concord, delights in concord, a speaker of words that promote concord. Abandoning harsh speech, he abstains from harsh speech; he speaks such words as are gentle, pleasing to the ear, and loveable, as go to the heart, are courteous, desired by many, and agreeable to many. Abandoning idle chatter, he abstains from idle chatter; he speaks at the right time, speaks what is fact, speaks on what is good, speaks on the Dhamma and the Discipline; at the right time he speaks such words as are worth recording, reasonable, moderate, and beneficial. That is how there are four kinds of righteous verbal conduct, conduct in accordance with the Dhamma.
Right action
Abstinence from the destruction of life, abstinence from taking what is not given, abstinence from sexual misconduct: this is called right action.
“And how, householders, are there three kinds of righteous bodily conduct, conduct in accordance with the Dhamma? Here someone, abandoning the destruction of life, abstains from the destruction of life; with rod and weapon laid aside, conscientious, merciful, he dwells compassionate to all living beings. Abandoning the taking of what is not given, he abstains from taking what is not given; he does not take by way of theft the wealth and property of others in the village or in the forest. Abandoning sexual misconduct, he abstains from sexual misconduct; he does not have intercourse with women who are protected by their mother, father, mother and father, brother, sister, or relatives, who have a husband, who are protected by law, or with those already engaged. That is how there are three kinds of righteous bodily conduct, conduct in accordance with the Dhamma.
Right livelihood
Here a noble disciple, having abandoned a wrong mode of livelihood, earns his living by a right livelihood: this is called right livelihood.
“These five trades, O monks, should not be taken up by a lay follower: trading in weapons, trading in living beings, trading in meat, trading in intoxicants, trading in poison.” (AN 5:177; III 208)
Right effort
Here, monks, a monk generates desire for the nonarising of unarisen evil unwholesome states; he makes an effort, arouses energy, applies his mind, and strives. He generates desire for the abandoning of arisen evil unwholesome states…. He generates desire for the arising of unarisen wholesome states…. He generates desire for the continuation of arisen wholesome states, for their nondecline, increase, expansion, and fulfillment by development; he makes an effort, arouses energy, applies his mind, and strives. This is called right effort.
“Friends, when a bhikkhu reviews himself thus, if he sees that these evil unwholesome states are not all abandoned in himself, then he should make an effort to abandon them all. But if, when he reviews himself thus, he sees that they are all abandoned in himself, then he can abide happy and glad, training day and night in wholesome states.216
Right mindfulness
Here, monks, a monk dwells contemplating the body in the body, ardent, clearly comprehending, mindful, having removed longing and dejection in regard to the world. He dwells contemplating feelings in feelings, ardent, clearly comprehending, mindful, having removed longing and dejection in regard to the world. He dwells contemplating mind in mind, ardent, clearly comprehending, mindful, having removed longing and dejection in regard to the world. He dwells contemplating phenomena in phenomena, ardent, clearly comprehending, mindful, having removed longing and dejection in regard to the world. This is called right mindfulness.
A.K.A. The Four Establishments of Mindfulness
Right concentration
Here, monks, secluded from sensual pleasures, secluded from unwholesome states, a monk enters and dwells in the first jhāna, which is accompanied by thought and examination, with rapture and happiness born of seclusion. With the subsiding of thought and examination, he enters and dwells in the second jhāna, which has internal confidence and unification of mind, is without thought and examination, and has rapture and happiness born of concentration. With the fading away as well of rapture, he dwells equanimous and, mindful and clearly comprehending, he experiences happiness with the body; he enters and dwells in the third jhāna of which the noble ones declare: ‘He is equanimous, mindful, one who dwells happily.’ With the abandoning of pleasure and pain, and with the previous passing away of joy and dejection, he enters and dwells in the fourth jhāna, which is neither painful nor pleasant and includes the purification of mindfulness by equanimity. This is called right concentration.”
“Suppose a forest deer is wandering in the forest wilds: he walks confidently, stands confidently, sits confidently, lies down confidently. Why is that? Because he is out of the hunter’s range. So too, quite secluded from sensual pleasures, secluded from unwholesome states, a bhikkhu enters upon and abides in the first jhāna, which is accompanied by applied and sustained thought, with rapture and pleasure born of seclusion. This bhikkhu is said to have blindfolded Māra, to have become invisible to the Evil One by depriving Māra’s eye of its opportunity.317 35. “Again, with the stilling of applied and sustained thought, a bhikkhu enters upon and abides in the second jhāna, which has self-confidence and singleness of mind without applied and sustained thought, with rapture and pleasure born of concentration. This bhikkhu is said to have blindfolded Māra… 36. “Again, with the fading away as well of rapture, a bhikkhu abides in equanimity, and mindful and fully aware, still feeling pleasure with the body, he enters upon and abides in the third jhāna, on account of which noble ones announce: ‘He has a pleasant abiding who has equanimity and is mindful.’ This bhikkhu is said to have blindfolded Māra… 37. “Again, with the abandoning of pleasure and pain, and with the previous disappearance of joy and grief, a bhikkhu enters upon and abides in the fourth jhāna, which has neither-pain-nor-pleasure and purity of mindfulness due to equanimity. This bhikkhu is said to have blindfolded Māra… 38. “Again, with the complete surmounting of perceptions of form, with the disappearance of perceptions of sensory impact, with non-attention to perceptions of diversity, aware that ‘space is infinite,’ a bhikkhu enters upon and abides in the base of infinite space. This bhikkhu is said to have blindfolded Māra… 39. “Again, by completely surmounting the base of infinite space, aware that ‘consciousness is infinite,’ a bhikkhu enters upon and abides in the base of infinite consciousness. This bhikkhu is said to have blindfolded Māra… 40. “Again, by completely surmounting the base of infinite consciousness, aware that ‘there is nothing,’ a bhikkhu enters upon and abides in the base of nothingness. This bhikkhu is said to have blindfolded Māra… 41. “Again, by completely surmounting the base of nothingness, [175] a bhikkhu enters upon and abides in the base of neither-perception-nor-non-perception. This bhikkhu is said to have blindfolded Māra, to have become invisible to the Evil One by depriving Māra’s eye of its opportunity. 42. “Again, by completely surmounting the base of neither-perception-nor-non-perception, a bhikkhu enters upon and abides in the cessation of perception and feeling. And his taints are destroyed by his seeing with wisdom. This bhikkhu is said to have blindfolded Māra, to have become invisible to the Evil One by depriving Māra’s eye of its opportunity, and to have crossed beyond attachment to the world.318 He walks confidently, stands confidently, sits confidently, lies down confidently. Why is that? Because he is out of the Evil One’s range.”
That is what the Blessed One said. The bhikkhus were satisfied and delighted in the Blessed One’s words.
