The Eightfold Path is a core Buddhist teaching that outlines the way to end suffering and achieve enlightenment. It consists of eight interconnected practices divided into wisdom, ethical conduct, and mental discipline, which are meant to be developed simultaneously. Originating from the Buddha's first sermon, the Eightfold Path is a practical guide to living a moral and fulfilling life. It emphasizes understanding reality, cultivating wholesome thoughts, practicing ethical behavior, and developing mental clarity through meditation and mindfulness.
