Buddhism is centered around the Four Noble Truths, which explain the nature of suffering and the path to its cessation. The first truth acknowledges that suffering, or dukkha, is an inherent part of life. The second identifies the cause of suffering as craving and attachment. The third truth states that it is possible to end suffering, while the fourth outlines the Noble Eightfold Path as a guide to achieve this. Another key concept in Buddhism is karma, which refers to the law of moral causation. It suggests that actions have consequences, influencing future experiences. Additionally, the idea of nirvana represents the ultimate goal of liberation from the cycle of birth and rebirth, or samsara, leading to a state of peace and enlightenment.
