Four Noble Truths
The Four Noble Truths (or The Four Truths of the Noble Ones[1]) (Sanskrit: catvāri āryasatyāni; Wylie: 'phags pa'i bden pa bzhi; Pali: cattāri ariyasaccāni) is one of the most fundamental Buddhist teachings. This Dharma Enlightenment makes ordinary person become the Buddha (Khun Weera Boontanorm, 2000). In broad terms, these truths relate to suffering (or dukkha), its nature, its origin, its cessation and the path leading to its cessation. They are among the truths Siddhartha Gautama is said to have realized during his experience of enlightenment.[2]
The Four Noble Truths appear many times, throughout the most ancient Buddhist texts, the Pali Canon. The early teaching and the traditional understanding in Theravada is that the Four Noble Truths are an advanced teaching for those who are ready for them.
The Sanskrit and Pali words satya and sacca, respectively, mean both "truth" and "real" or "actual thing." With that in mind, one scholar argues that it is important to recognize that the four noble truths are not asserted as propositional truths or creeds, but as "true things" or "realities" that the Buddha experienced.[3] The original Tibetan Lotsawas (Sanskrit: locchāwa; Tibetan: lo ts'a ba), who studied Sanskrit grammar thoroughly, used the Tibetan term bden pa, reflects this understanding.
Background
Why the Buddha is said to have taught in this way is illuminated by the social context of the time in which he lived. The Buddha was a Śramaṇa – a wandering ascetic whose "aim was to discover the truth and attain happiness."[4] He is said to have achieved this aim while under a bodhi tree near the River Neranjana; the Four Noble Truths are a formulation of his understanding of the nature of "suffering",[5] the fundamental cause of all suffering, the escape from suffering, and what effort a person can go to so that they themselves can "attain happiness."[4]
These truths are not expressed as a hypothesis or tentative idea; rather, the Buddha says:
These Four Noble Truths, monks, are actual, unerring, not otherwise. Therefore, they are called noble truths.[6]
The Buddha says that he taught them...
...because it is beneficial, it belongs to the fundamentals of the holy life, it leads to disenchantment, to dispassion, to cessation of suffering, to peace, to direct knowledge, to enlightenment, to Nirvana. That is why I have declared it.[7]
This teaching was the basis of the Buddha's first discourse after his enlightenment.[8] In early Buddhism this is the most advanced teaching in the Buddha's Gradual Training.
Pali and Chinese canon text
1.The Nature of Suffering (Dukkha):
"This is the noble truth of suffering: birth is suffering, aging is suffering, illness is suffering, death is suffering; sorrow, lamentation, pain, grief and despair are suffering; union with what is displeasing is suffering; separation from what is pleasing is suffering; not to get what one wants is suffering; in brief, the five aggregates subject to clinging are suffering."[8][9]
2.Suffering's Origin (Samudaya):"This is the noble truth of the origin of suffering: it is this craving which leads to renewed existence, accompanied by delight and lust, seeking delight here and there, that is, craving for sensual pleasures, craving for existence, craving for extermination."[8][9]
3.Suffering's Cessation (Nirodha):"This is the noble truth of the cessation of suffering: it is the remainderless fading away and cessation of that same craving, the giving up and relinquishing of it, freedom from it, nonreliance on it."[8][9]
4.The Way (Magga) Leading to the Cessation of Suffering:
"This is the noble truth of the way leading to the cessation of suffering: it is the Noble Eightfold Path; that is, right view, right intention, right speech, right action, right livelihood, right effort, right mindfulness, right concentration."[10][11]
