Schools of Buddhism
The schools of Buddhism are the various institutional and doctrinal divisions of Buddhism that have existed from ancient times up to the present. The classification and nature of various doctrinal, philosophical or cultural facets of the schools of Buddhism is vague and has been interpreted in many different ways, often due to the sheer number (perhaps thousands) of different sects, subsects, movements, etc. that have made up or currently make up the whole of Buddhist traditions. The sectarian and conceptual divisions of Buddhist thought are part of the modern framework of Buddhist studies, as well as comparative religion in Asia.
From a largely English-language standpoint, and to some extent in most of Western academia, Buddhism is separated into two groups: Theravāda (lit. 'the Teaching of the Elders' or 'the Ancient Teaching'), and Mahāyāna (lit. 'the Great Vehicle'). The most common classification among scholars is threefold: Theravāda, Mahāyāna and Vajrayāna.
In contemporary Buddhist studies, modern Buddhism is often divided into three major branches, traditions or categories:[1][2][3][4]
Another way of classifying the different forms of Buddhism is through the different monastic ordination traditions. There are three main traditions of monastic law (Vinaya) each corresponding to the first three categories outlined above:
Theravāda is the only extant mainstream non-Mahayana school. They are derived from the Sri Lankan Mahāvihāra sect, which was a branch of the South Indian Vibhajjavādins. Theravāda bases its doctrine on the Pāli Canon, the only complete Buddhist canon surviving in a classical Indian language. This language is Pāli, which serves as the school's sacred language and lingua franca.[31]
The different sects and groups in Theravāda often emphasize different aspects (or parts) of the Pāli canon and the later commentaries (especially the very influential Visuddhimagga), or differ in the focus on and recommended way of practice. There are also significant differences in strictness or interpretation of the Vinaya Pitaka, the Theravādin Vinaya followed by monastics of this tradition.
The various divisions in Theravāda include:
Esoteric Buddhism, also known as Vajrayāna, Mantrayāna, Tantrayāna, Secret Mantra, and Tantric Buddhism is often placed in a separate category by scholars due to its unique tantric features and elements. Esoteric Buddhism arose and developed in medieval India among esoteric adepts known as Mahāsiddhas. Esoteric Buddhism maintains its own set of texts alongside the classic scriptures, these esoteric works are known as the Buddhist Tantras. It includes practices that make use of mantras, dharanis, mudras, mandalas and the visualization of deities and Buddhas.
Main Esoteric Buddhist traditions include:
Various Buddhist new religious movements arose in the 20th century, including the following.
