Today's episode of Boing Boing tv is a new installment of our "BBtv World" series, in which we bring you first-person accounts of life around the world. In this episode, I traveled to Lhasa during an annual festival in the Tibetan Buddhist calendar.

The first thing that hits you when you arrive in Lhasa is just how close to the heavens you are. Literally. The average elevation is 16,000 feet. The fact that this place is known as the “Roof of the World" makes sense as your newcomer lungs and blood struggle to adjust to the altitude.

Beijing says Tibet is historically part of China, not a sovereign nation. China’s army invaded Tibet in 1950. Years of bloody conflict followed. In 1959, Tibet’s traditional spiritual leader, the Dalai Lama, fled into exile in India. China has governed over Tibet since then.

During the fourth lunar month in the Tibetan calendar, ethnic Tibetans celebrate the annual festival of Saga Dawa. Tibetan Buddhists believe that on the full moon in this month, in various years of his life, the Buddha was born, achieved enlightenment, and died.

A large armed police presence surrounded the festival during the year I shot the footage you'll see in this episode. When we asked one pilgrim why, she said “Because when too many Tibetans gather in one place, they are afraid we’ll rise up.”

In 2008, Saga Dawa fell on the heels of a violent government crackdown on pro-independence protesters throughout Tibet, with large numbers of "suspects" rounded up and jailed. Widespread reports of human rights abuses filtered out, despite a virtual communications blackout. This year’s festival also fell near the anniversary of the Tiananmen democracy protests.

While first-person accounts were hard to come by, there were many reports of ethnic Tibetans being blocked from the traditional Lingkor circumambulation around Lhasa in the name of state security.
