c. 563-483 BCE (traditional) or c. 480-400 BCE (scholarly)
All beings experience a restless dissatisfaction — an innate, relentless urge to grasp, acquire, and achieve, which can never be fully satisfied. The Buddha offers a formula — the Four Noble Truths — that diagnoses this condition and provides a practical path to liberation from the endless cycle of birth, death, and rebirth, leading ultimately to Nirvana, a state beyond words or conception.
Siddhartha Gautama was born around 480 BCE (revised scholarly dating) in Lumbini, son of a chieftain of the Shakya clan in the Himalayan foothills. Legend encrusted his life early, but the core story rings with psychological truth.
His father received a prophecy: the boy would become a universal monarch or a universal teacher. Wanting a king, not a sage, Suddhodana surrounded Siddhartha with pleasure and hid all suffering from him. The prince grew up in gilded isolation, married the beautiful Yasodhara, fathered a son he named Rahula (“fetter”).
At 29, venturing outside the palace, he encountered the Four Sights: an old man, a sick man, a corpse, and a wandering ascetic. The first three revealed the truth his father had hidden — all beings age, sicken, and die. The fourth suggested a response: one could leave society to seek what lies beyond suffering.
That night, Siddhartha kissed his sleeping wife and son and slipped away. He cut his hair, exchanged his royal robes for rags, and began seeking. For six years, he studied with teachers, mastered meditation techniques, and practised extreme asceticism — fasting until he could feel his spine through his stomach. Nothing worked. The teachers offered temporary peace; asceticism brought only weakness.
Abandoning extremes, he sat beneath a pipal tree at Bodh Gaya, vowing not to rise until he found the answer. That night, he saw his past lives, understood the mechanism of karma, and realised the Four Noble Truths: suffering exists; craving causes it; cessation is possible; the Eightfold Path leads there. He had awakened. He was Buddha.
For 45 years, he walked the Gangetic plain, teaching anyone who would listen — kings, merchants, outcasts, women, criminals. He established the Sangha (monastic community), the first organised alternative to Brahmanical religion. He refused to answer metaphysical questions — is the universe eternal? is the soul identical with the body? — calling them “not conducive to liberation.” He taught only what he had verified: the diagnosis and cure for suffering.
He died at 80, after eating spoiled food offered by a blacksmith named Cunda. He told his distraught disciples to blame no one — Cunda’s gift was meritorious. His final words urged them to be their own lamps, work out their own salvation. Then he entered parinirvana — final cessation, beyond rebirth.
"Life is suffering (dukkha)."
— First Noble Truth — the starting point of Buddhist philosophy; dukkha also means "unsatisfactoriness"
"Hatred never ceases by hatred; hatred ceases only by love. This is an ancient and eternal law."
— Dhammapada 5 — ethics distilled
"Be a lamp unto yourself. Work out your salvation with diligence."
— Final teaching before death — Mahaparinibbana Sutta
The Buddha’s teaching is a diagnosis and cure. The diagnosis: life is dukkha — suffering, unsatisfactoriness, dis-ease. Not just pain but the inability of any experience to fully satisfy. Even pleasure is dukkha because it ends, and we crave its return.
The cause is tanha — craving, thirst, grasping. We want what we don’t have; we want to keep what we have; we want to be something we’re not. Craving creates attachment; attachment creates suffering when things change — and things always change.
The cure is possible. Nirvana (literally “blowing out”) is the cessation of craving, and with it, the cessation of suffering. It is not annihilation but liberation — the fire goes out not into nothingness but simply out, no longer burning.
The path is the Noble Eightfold Path: Right View, Right Intention, Right Speech, Right Action, Right Livelihood, Right Effort, Right Mindfulness, Right Concentration. These group into wisdom (understanding the Four Noble Truths), ethics (not harming), and meditation (training the mind). The path is a middle way between luxury and asceticism — neither indulgence nor mortification.
Behind this practical teaching lies a radical metaphysics, usually presented therapeutically. The Three Marks of Existence: all conditioned things are impermanent (anicca), unsatisfactory (dukkha), and without self (anatta). The last is revolutionary. There is no atman, no eternal soul, no unchanging self. What we call “self” is a constantly changing process — five aggregates (skandhas) of form, sensation, perception, mental formations, and consciousness, rising and falling in mutual dependence.
If there’s no self, what is reborn? The question assumes what Buddhism denies — a thing that transmits. Instead, causal continuity: this life’s craving conditions the next, like a flame lighting a new candle. The flame is not “the same” flame, but it’s not unconnected either.
The Buddha famously refused to answer certain questions: Is the universe eternal? Is the soul identical with the body? Does the Tathagata exist after death? These are “questions not conducive to liberation” — net-like speculations that trap the mind. Philosophy in Buddhism is medicine. You don’t need to know the origin of the arrow poisoning you; you need to remove it.
