Buddhism ( /ˈbʊdɪzəm/ or /ˈbuːdɪzəm/) is a religion and dharma that encompasses a variety of traditions, beliefs and spiritual practices largely based on original teachings attributed to the Buddha and resulting interpreted philosophies. Buddhism originated in ancient India sometime between the 6th and 4th centuries BCE, from where it spread through much of Asia, whereafter it declined in India during the Middle Ages. Two major extant branches of Buddhism are generally recognized by scholars: Theravada (Pali: "The School of the Elders") and Mahayana (Sanskrit: "The Great Vehicle"). Buddhism is the world's fourth-largest religion, with over 520 million followers or over 7% of the global population, known as Buddhists.
Buddhist schools vary on the exact nature of the path to liberation, the importance and canonicity of various teachings and scriptures, and especially their respective practices. Practices of Buddhism include taking refuge in the Buddha, the Dharma and the Sangha, study of scriptures, observance of moral precepts, renunciation of craving and attachment, the practice of meditation (including calm and insight), the cultivation of wisdom, loving-kindness and compassion, the Mahayana practice of bodhicitta and the Vajrayana practices of generation stage and completion stage.
