Geography
The island of Bali lies 3.2 km (2 mi) east of Java, and is approximately 8 degrees south of the equator. East to west, the island is approximately 153 km (95 mi) wide and spans approximately 112 km (69 mi) north to south; its land area is 5,632 km².

The highest point is Mount Agung at 3,142 m (9,426 feet) high, an active volcano that last erupted in March 1963. Mountains range from centre to the eastern side, with Mount Agung the easternmost peak. Mount Batur (1,717 m) is also still active; an eruption 30,000 years ago was one of the largest known volcanic events on Earth.In the south the land descends to form an alluvial plain, watered by shallow, north-south flowing rivers, drier in the dry season and overflowing during periods of heavy rain. The longest of these rivers, Sungai Ayung, flows approximately 75 km.

The principal city is the provincial capital and largest city, Denpasar, near the southern coast. Its population is around 300,000. Bali’s second-largest city is the old colonial capital, Singaraja, which is located on the north coast and is home to around 100,000 people. Other important cities include the beach resort, Kuta, which is practically part of Denpasar’s urban area; and Ubud, which is north of Denpasar, and is known as the island’s cultural centre.

Three small islands lie to the immediate south east of Bali and all are administratively part of the Klungkung regency of Bali: Nusa Penida, Nusa Lembongan and Nusa Ceningan. These islands are separated from Bali by the Badung Strait.

Culture
Bali is renowned for its diverse and sophisticated art forms, such as painting, sculpture, woodcarving, handcrafts, and performing arts. Balinese percussion orchestra music, known as gamelan, is highly developed and varied. Balinese performing arts often portray stories from Hindu epics such as the Ramayana but with heavy Balinese influence. Famous Balinese dances include pendet, legong, baris, topeng, barong, gong keybar, and kecak (the monkey dance). Bali boasts one of the most diverse and innovative performing arts cultures in the world, with paid performances at thousands of temple festivals, private ceremonies, or public shows.

The Hindu New Year, Nyepi, is celebrated in the spring by a day of silence. On this day everyone stays at home and tourists are encouraged to remain in their hotels. But the day before that large, colourful sculptures of ogoh-ogoh monsters are paraded and finally burned in the evening to drive away evil spirits. Other festivals throughout the year are specified by the Balinese pawukon calendrical system.

Celebrations are held for many occasions such as a tooth-filing (coming-of-age ritual), cremation or odalan (temple festival). One of the most important concepts that Balinese ceremonies have in common is that of désa kala patra, which refers to how ritual performances must be appropriate in both the specific and general social context. Many of the ceremonial art forms such as wayang kulit and topeng are highly improvisatory, providing flexibility for the performer to adapt the performance to the current situation.Many celebrations call for a loud, boisterous atmosphere with lots of activity and the resulting aesthetic, ramé, is distinctively Balinese. Oftentimes two or more gamelan ensembles will be performing well within earshot, and sometimes compete with each other in order to be heard. Likewise, the audience members talk amongst themselves, get up and walk around, or even cheer on the performance, which adds to the many layers of activity and the liveliness typical of ramé.

Tourism, Bali’s chief industry, has provided the island with a foreign audience that is eager to pay for entertainment, thus creating new performance opportunities and more demand for performers. The impact of tourism is controversial since before it became integrated into the economy, the Balinese performing arts did not exist as a capitalist venture, and were not performed for entertainment outside of their respective ritual context. Since the 1930’s sacred rituals such as the barong dance have been performed both in their original contexts, as well as exclusively for paying tourists. This has led to new versions of many of these performances which have developed according to the preferences of foreign audiences; some villages have a barong mask specifically for non-ritual performances as well as an older mask which is only used for sacred performances.

Religion
Unlike most of Muslim-majority Indonesia, about 93.18% of Bali’s population adheres to Balinese Hinduism, formed as a combination of existing local beliefs and Hindu influences from mainland Southeast Asia and South Asia. Minority religions include Islam (4.79%), Christianity (1.38%), and Buddhism (0.64%). These figures do not include immigrants from other parts of Indonesia.

Balinese Hinduism is an amalgam in which gods and demigods are worshipped together with Buddhist heroes, the spirits of ancestors, indigenous agricultural deities and sacred places. Religion as it is practiced in Bali is a composite belief system that embraces not only theology, philosophy, and mythology, but ancestor worship, animism and magic. It pervades nearly every aspect of traditional life.

Balinese Hinduism has roots in Indian Hinduism and in Buddhism, and adopted the animistic traditions of the indigenous people. This influence strengthened the belief that the gods and goddesses are present in all things. Every element of nature, therefore, possesses its own power, which reflects the power of the gods. A rock, tree, dagger, or woven cloth is a potential home for spirits whose energy can be directed for good or evil. Balinese Hinduism is deeply interwoven with art and ritual, and is less preoccupied with scripture, law, and belief than Islam in Indonesia. Ritualizing states of self-control are a notable feature of religious expression among the people, who for this reason have become famous for their graceful and decorous behavior.
