What are the key principles of Buddhism?

Buddhism is a religion and philosophy that originated in ancient India and is based on the teachings of Siddhartha Gautama, also known as the Buddha. The key principles of Buddhism include the Four Noble Truths, the Eightfold Path, and the concept of impermanence. The Four Noble Truths describe the nature of suffering and the path to its cessation. The Eightfold Path outlines a way of life that leads to the end of suffering and the attainment of enlightenment. It consists of right understanding, right intention, right speech, right action, right livelihood, right effort, right mindfulness, and right concentration. Impermanence is the understanding that all things are constantly changing and that attachment to anything is the root of suffering.
