What are the three major traditions of Buddhism and how do they differ?

The three major traditions of Buddhism are Theravada, Mahayana, and Vajrayana. Theravada, often considered the oldest, emphasizes individual enlightenment through meditation and the monastic community, primarily practiced in countries like Sri Lanka and Thailand. Mahayana broadens the focus to include the Bodhisattva ideal, encouraging practitioners to seek enlightenment for the sake of all beings, and is prevalent in East Asia. Vajrayana, often viewed as an extension of Mahayana, incorporates esoteric practices and rituals, and is most commonly associated with Tibetan Buddhism.
