Buddhism definition and meaning: a major world religious and philosophical tradition. More than 500 million people practice it worldwide. Rooted in the teachings of the Buddha, it offers a path for understanding suffering and cultivating wisdom. It also guides practitioners toward living ethically through meditation, moral discipline, and insight. Over time, Buddhism developed diverse traditions. These traditions fall into three main groups: Theravada, Mahayana, and Vajrayana. All three share core principles, including karma, compassion, and awakening.
