The Bhutanese constitution guarantees freedom of religion and citizens and visitors are free to practice any form of worship so long as it does not impinge on the rights of others. Christianity, Hinduism and Islam are also present in the country.
Buddhism: Bhutan is a Buddhist country and people often refer to it as the last stronghold of Vajrayana Buddhism. Buddhism was first introduced by the Indian Tantric master Guru Padmasambhava in the 8th century. Until then the people practiced Bonism, a religion that worshiped all forms of nature, remnants of which are still evident in some remote villages in the country.
With the visit of Guru Padmasambhava, Buddhism began to take firm roots within the country and this especially led to the propagation of the Nyingmapa (the ancient or the older) school of Buddhism.
Phajo Drugom Zhigp from Ralung in Tibet was instrumental in introducing yet another school of Buddhism – the Drukpa Kagyu sect. In 1222 he came to Bhutan, an event of great historical significance and a major milestone for Buddhism in Bhutan, and established the DrukpaKagyu sect of Buddhism, the state religion. His sons and descendants were also instrumental in spreading it to many other regions of western Bhutan.
By far the greatest contributor was Zhabdrung Nawang Namgyal. His arrival in 1616 from Tibet was another landmark event in the history of the nation. He brought the various Buddhist schools that had developed in western Bhutan under his domain and unified the country as one whole nation-state giving it a distinct national identity.
The Buddhism practiced in the country today is a vibrant religion that permeates nearly every facet of the Bhutanese life style. It is present in the Dzongs, monasteries, stupas, prayer flags, and prayer wheels punctuate the Bhutanese landscape. The chime of ritual bells, sound of gongs, people circumambulating temples and stupas, fluttering prayer flags, red robed monks conducting rituals stand as testaments to the importance of Buddhism in Bhutanese life.
