Buddhism is practiced through out the country. All most all the Bhutanese are Buddhist. In the south, most Bhutanese people of Nepali and Indian origin practiced Hinduism. Yeshi Gonpo or Mahakahala is the main protective deity of Bhutan, often appears in the form of Raven.
Before the arrival of Buddhism to Bhutan, various forms of animistic religion such as bonism were followed by people in Bhutan. In some parts of the country, we can still see, these traditions and rituals are still practiced by minority groups.
Guru Rinpoche brought Buddhism to Bhutan in 8th century. After this, Bhutan has become home to many sages and saints. Some of the key figures of the Bhutanese Buddhism are Kuenkhen Longchen Ramjam, Phojo Drukgom Zhigpo, Drukpa Kuenley, Zhabdrung Ngwang Namgyel and Gyalse Tenzin Rabgye.
The official state religion of Bhutan belongs to the Drukpa sect of Kagyudpa, school of tantric Mahayana Buddhism, the Great Vehicle. It is similar to the Tibetan Buddhism, yet it has its own set of unique beliefs and practices.
The religion in Bhutan is strongly supported by the all walks of life. Monks, nuns and gomchens (lay priest) play a very important role in the people’s daily lives. The monk body also includes monks, nuns and gomchens who are not part of state sponsored institutions.
The National language of Bhutan is Dzongkha and literally Dzongkha means the language spoken in the Dzongs and administrative centers in all the districts of Bhutan. But the Dzongkha was the language spoken by the people of Western Bhutan.
