Theravada Buddhism is by far the most prominent organized religion in the country, with nearly 5,000 temples serving as the focus of religious practice as well as the center of community life in rural areas. In most lowland Lao villages, religious tradition remains strong. Most Buddhist men spend some part of their lives as monks in temples, even if only for a few days.
There are approximately 22,000 monks in the country, nearly 9,000 of whom have attained the rank of "senior monk," indicating years of study in temples. In addition, there are approximately 450 nuns, generally older women who are widowed, residing in temples throughout the country. The Buddhist Church is under the direction of a supreme patriarch who resides in Vientiane and supervises the activities of the church's central office, the Ho Thammasaphat has the 20% of the populations.
Lao Buddhists belong to the Theravada tradition, based on the earliest teachings of the Buddha and preserved in Sri Lanka after Mahayana Buddhism branched off in the second century B.C. Theravada Buddhism is also the dominant school in neighboring Myanmar, Thailand and Cambodia
