The Buddha and the Four Noble Truths
The Birth and Early Life of the Buddha
The historical Buddha was born Siddhartha Gautama, traditionally dated around the 5th century BCE in Lumbini (in present-day Nepal). According to Buddhist tradition, his father Suddhodana was a ruler of the Shakya clan, and at the time of his birth, a seer prophesied that the child would become either a great king or a great spiritual teacher. His father, wishing his son to take the kingly path, surrounded the young prince with every luxury and shielded him entirely from the realities of suffering, old age and death. Siddhartha grew up in a palace, married young, and fathered a son named Rahula. By all outward measures, his life was one of wealth, pleasure and security.
The Four Sights
The turning point came when Siddhartha ventured outside the palace grounds on four separate occasions, encountering what tradition calls the Four Sights. These encounters are described in later Buddhist biographical tradition. The early Pali Canon (DN 14, Mahapadana Sutta) records similar encounters in the life of a previous Buddha, Vipassi; the narrative as applied to Siddhartha develops in later texts such as the Nidanakatha. First, he saw a sick person in great pain — a sight unknown to him in his sheltered life. Second, he encountered an old person, frail and bent with age. Third, he saw a corpse being carried in a funeral procession — the reality of death made visible. Each encounter was a revelation: these were the universal conditions of human life, not exceptions. The fourth sight was decisive: he saw a wandering holy man (a samana) who appeared calm and at peace despite having nothing. This figure planted the idea that peace was possible even amid impermanence and death.
Moved by what he had seen, Siddhartha left the palace at night, abandoning his wife, son, wealth and status. This is known as the “Great Renunciation.” He set off to seek the truth about suffering and its end.
After leaving the palace, Siddhartha studied under two teachers of deep meditation but felt these paths were incomplete. He then joined a group of five ascetics and practised extreme self-mortification — eating almost nothing, enduring heat and cold, and pushing his body to the limit. He nearly died. Eventually he recognised that the path of extreme asceticism, like the path of extreme luxury, would not lead to liberation. He accepted food from a young woman named Sujata and, restored in strength, sat beneath the Bodhi tree at Bodh Gaya. This insight — that neither extreme luxury nor extreme asceticism leads to liberation, but a balanced “Middle Way” — became a foundational principle of Buddhist teaching and practice.
Enlightenment
Sitting under the Bodhi tree at Bodh Gaya, Siddhartha entered deep meditation and, during the night, attained Enlightenment (Pali: bodhi). He saw clearly the nature of suffering, its causes, the possibility of its cessation, and the path leading to that cessation — what would become the Four Noble Truths. He understood dependent arising, the Three Marks of Existence and the law of kamma (moral causation). From that moment he was the Buddha — the “Awakened One.” He then delivered his first teaching at Sarnath, setting in motion the Wheel of the Dhamma.
The Four Noble Truths are: 1) Dukkha — the truth of suffering; 2) Samudaya — the truth of the origin of suffering (rooted in tanha, craving); 3) Nirodha — the truth of the cessation of suffering (nibbana); 4) Magga — the truth of the path leading to the cessation of suffering (the Eightfold Path).
The First Noble Truth: Dukkha
The first truth acknowledges that dukkha is a universal feature of unenlightened human experience. This includes obvious suffering (pain, grief, illness), the suffering of impermanence (pleasures that cannot last), and the pervasive unsatisfactoriness of existence that has not yet found liberation. The first truth is not pessimism — it is a clear-eyed diagnosis.
The Second Noble Truth: Samudaya
The second truth identifies the origin of suffering as tanha (craving or thirst). The Buddha identified three forms of craving: craving for sense pleasures, craving for existence (wanting things to continue), and craving for non-existence (wanting things to stop). Underlying tanha are the Three Poisons — the Three Poisons of ignorance (moha), greed (lobha) and hatred (dosa). Ignorance is considered the deepest root because it produces the false belief in a fixed, permanent self, from which greed and hatred then arise.
The Third and Fourth Noble Truths: Nirodha and Magga
The third truth teaches that suffering can cease. When craving is completely extinguished, nibbana (Sanskrit: nirvana) is attained. Nibbana is sometimes described negatively — as the “blowing out” of the fires of greed, hatred and ignorance — but Buddhist teachers are careful to say it is not mere annihilation. It is beyond the categories of existence and non-existence. The fourth truth points to the practical path: the Eightfold Path (magga), structured as the Threefold Way of ethics, meditation and wisdom, which leads the practitioner step by step toward nibbana.
The Three Poisons are the root causes of suffering underlying tanha (craving): ignorance (moha) — the false belief in a fixed self; greed (lobha) — clinging to pleasure and existence; hatred (dosa) — aversion to unwanted experience. The Eightfold Path removes all three.
Theravada Buddhism describes nibbana in terms of the complete cessation of the Three Poisons and the end of rebirth. The Arhat who attains “final nibbana” (parinibbana) at death will not be reborn. Mahayana Buddhism retains the goal of liberation from suffering but tends to describe it in more positive terms: as Buddhahood, the full blossoming of Buddha-nature, characterised by wisdom and compassion. For Mahayana Bodhisattvas, who delay their own final liberation to help others, nibbana is not a solitary escape but the eventual liberation of all sentient beings. Both traditions agree that the cessation of craving and the Three Poisons is central; they differ in their descriptions of what is attained and how.
