Padmasambhava , meaning "the Lotus-Born," was a sageguru from Oddiyāna (Tibetan: Orgyen, Wylie: u rgyan) who is said to have transmitted Vajrayana Buddhism to Bhutan, Tibet and neighboring countries in the 8th century AD.
In those lands he is better known as Guru Rinpoche ("Precious Guru") or Lopon Rinpoche, or as Padum in Tibet, where followers of the Nyingma school regard him as the second Buddha.
Bhutan existed as a patchwork of minor warring fiefdoms until the early 17th century, when the lama and military leader ShabdrungNgawang Namgyal, fleeing religious persecution in Tibet, unified the area and cultivated a distinct Bhutanese identity. Later, in the early 20th century, Bhutan came into contact with the British Empire and retained strong bilateral relations with India upon its independence. In 2006, based on a global survey, Business Week rated Bhutan the happiest country in Asia and the eighth-happiest in the world.
