I teach suffering, its origin, cessation and path. That's all I teach", declared the Buddha 2500 years ago. The Four Noble Truths contain the essence of the Buddha's teachings. It was these four principles that the Buddha came to understand during his meditation under the bodhi tree.
  1. The truth of suffering (Dukkha)
  2. The truth of the origin of suffering (Samudāya)
  3. The truth of the cessation of suffering (Nirodha)
  4. The truth of the path to the cessation of suffering (Magga)
The Buddha is often compared to a physician. In the first two Noble Truths he diagnosed the problem (suffering) and identified its cause. The third Noble Truth is the realisation that there is a cure. The fourth Noble Truth, in which the Buddha set out the Eightfold Path, is the prescription, the way to achieve a release from suffering. The First Noble Truth Suffering (Dukkha)
Suffering comes in many forms. Three obvious kinds of suffering correspond to the first three sights the Buddha saw on his first journey outside his palace: old age, sickness and death. But according to the Buddha, the problem of suffering goes much deeper. Life is not ideal: it frequently fails to live up to our expectations. Human beings are subject to desires and cravings, but even when we are able to satisfy these desires, the satisfaction is only temporary. Pleasure does not last; or if it does, it becomes monotonous. Even when we are not suffering from outward causes like illness or bereavement, we are unfulfilled, unsatisfied. This is the truth of suffering. Some people who encounter this teaching may find it pessimistic. Buddhists find it neither optimistic nor pessimistic, but realistic. Fortunately the Buddha's teachings do not end with suffering; rather, they go on to tell us what we can do about it and how to end it.
