Mahāvaṃsa in the context of "Anuradhapura"

Buddhism, a religion founded by Gautama Buddha, first arrived in modern-day Afghanistan through the conquests of Ashoka (r. 268–232 BCE), the third emperor of the Maurya Empire. Among the earliest notable sites of Buddhist influence in the country is a bilingual mountainside inscription in Greek and Aramaic that dates back to 260 BCE and was found on the rocky outcrop of Chil Zena near Kandahar.

Many prominent Buddhist monks were based in Afghanistan during this period: Menander I (r. 165–130 BCE), a Greco-Bactrian king, was a renowned patron of Buddhism and is immortalized in the Milinda Panha, a Pali-language Buddhist text; Mahadharmaraksita, a 2nd-century BCE Indo-Greek monk, is said to have led 30,000 Buddhist monks from "Alasandra, the city of the Yonas" (a colony of Alexander the Great, located approximately 150 kilometres or 93 miles to the north of modern-day Kabul) to Sri Lanka for the dedication of the Mahathupa in Anuradhapura, according to the Mahavamsa (Chap. XXIX); Lokaksema, a 2nd-century Kushan monk, travelled to the Chinese capital city of Luoyang during the reign of the Han dynasty, and was the first translator of Mahayana Buddhist scriptures into the Chinese language.

The Jaya Sri Maha Bodhi is a sacred Bo tree (Ficus religiosa) located in the Mahamewuna Garden, within the historic UNESCO World Heritage City of Anuradhapura, Sri Lanka. It is believed to be a tree grown from a cutting of the southern branch from the historical sacred bo tree, Sri Maha Bodhi, which was destroyed during the time of Emperor Ashoka, at Bodh Gaya in India, under which Siddhartha Gautama (Buddha) attained enlightenment. In 236 BC, the Buddhist nun Sangamitta Maha Theri, a daughter of Indian Emperor Ashoka, brought the tree cutting to Sri Lanka during the reign of Sinhalese King Devanampiya Tissa. At more than 2,300 years old, it is the oldest living human-planted tree in the world with a known planting date. The Mahāvaṃsa, or the great chronicle of the Sinhalese, provides an elaborate account of the establishment of the Jaya Sri Maha Bodhi on the Island and the subsequent development of the site as a major Buddhist pilgrimage site.

Today, the Jaya Sri Maha Bodhi is situated on a high terrace, about 6.5 meters above the ground, and surrounded by 4 other lower-level terraces with Bo trees called "Parivara Bodhi" planted for its protection. The site is currently administered by the Chief High Priest of Atamasthana and the Atamasthana Palakasabha, the administrative body of the Atamasthana. It receives millions of pilgrims each year. The site is open to visitors and continuously hosts numerous acts of worship throughout the year. However, access to the uppermost terrace where the bo tree is located is restricted due to the old age of the tree and various acts of vandalism it has endured throughout history, including a terrorist attack by the LTTE in 1985, where around 146 pilgrims were massacred.
