Southern Esoteric Buddhism

Southern Esoteric Buddhism and Borān Kammaṭṭhāna are terms used to refer to a collection of esoteric practices, views, and texts within Theravada Buddhism. Often known as Esoteric Theravada or Tantric Theravada, these labels highlight its parallel with tantric traditions—though it does not employ actual tantras.

L.S. Cousins defines this phenomenon as "a type of Southern Buddhism which links magical and ritual practices to a theoretical systematisation of the Buddhist path itself."

In the West, the study of Southern Esoteric Buddhism was pioneered by professor François Bizot and his colleagues at the École française d'Extrême-Orient. Their research, especially focusing on material discovered at Angkor, has been instrumental in revealing the complex interplay between orthodox Theravada doctrines and these esoteric practices.

Over the past two centuries, the Boran tradition has been marginalized by colonial governments and by the "Protestant Buddhist" movement—reformers who promote a strict "Pali Tipitaka only" sola scriptura approach and dismiss local practices as deviations from orthodox scriptural teachings. As such, the tradition stands in opposition to Buddhist modernism and Secular Buddhism.
