Four Noble Truths
사성제

The Four Noble Truths comprise the essence of Buddha's teachings.

They are: the truth of suffering, the truth of the cause of suffering, the truth of the end of suffering, and the truth of the path that leads to the end of suffering.

In simpler words: suffering exists; it has a cause; it has an end; and it has a cause to bring about its end.

The notion of suffering does not represent a negative world view.

It helps us to deal with the world as it is.

The concept of pleasure is acknowledged as fleeting.

Pursuit of pleasure only results in an unquenchable thirst.

The causes of suffering are afflictions.

The path to follow for the cessation of suffering is the Noble Eightfold Path.
