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.

Our day-to-day troubles may seem to have easily identifiable causes: thirst, pain from an injury, sadness from the loss of a loved one. In the second of his Noble Truths, though, the Buddha claimed to have found the cause of all suffering - and it is much more deeply rooted than our immediate worries.

The Buddha taught that the root of all suffering is desire, tanhā.

The Buddha taught that the way to extinguish desire, which causes suffering, is to liberate oneself from attachment.

This is the third Noble Truth - the possibility of liberation.

The final Noble Truth is the Buddha's prescription for the end of suffering. This is a set of principles called the Eightfold Path.

The Eightfold Path is also called the Middle Way: it avoids both indulgence and severe asceticism, neither of which the Buddha had found helpful in his search for enlightenment.
