The Four Noble Truths are fundamental teachings in Buddhism that outline the nature of suffering and the path to liberation. The first truth states that suffering, or dukkha, is an inherent part of life. The second truth identifies the cause of suffering as craving or attachment, which leads to dissatisfaction. The third truth offers hope by asserting that it is possible to end suffering by overcoming these cravings. Finally, the fourth truth presents the Noble Eightfold Path as a practical guide to achieving this liberation, emphasizing ethical conduct, mental discipline, and wisdom.
