Buddhism was brought to Pwo-speaking Karens in the late-1700s, and the Yedagon Monastery atop Mount Zwegabin became the leading center of Karen language Buddhist literature. Many millennial sects were founded throughout the 1800s, led by Karen Buddhist minlaung rebels. Two sects, Telakhon (or Telaku) and Leke, were founded in the 1860s. The Tekalu sect, founded in Kyaing and considered a Buddhist sect, is a mixture of spirit worship, Karen customs and worship of the future Buddha Metteyya. The Leke sect was founded on the western banks of the Thanlwin River, and is no longer associated with Buddhism (as followers do not venerate Buddhist monks). Followers believe that the future Buddha will return to Earth if they maintain their moral practices (following the Dhamma and precepts), and they practice vegetarianism, hold Saturday services and construct distinct pagodas. Several Buddhist socioreligious movements, both orthodox and heterodox, have arisen in the past century. Duwae, a type of pagoda worship, with animistic origins, is also practised.
