Theravada and Vajrayana are two distinct branches of Buddhism, each with its own practices, beliefs, and interpretations of the Buddha's teachings. Theravada, often referred to as the 'School of the Elders', emphasizes personal enlightenment through meditation and ethical living, whereas Vajrayana, known as 'Diamond Vehicle', incorporates esoteric practices, rituals, and the use of mantras to achieve enlightenment more rapidly. These differences reflect varying cultural influences and spiritual goals within the broader Buddhist tradition.
