The Jokhang Temple is dedicated to the statue of Jowo Shakyamuni. This is the holiest temple in all of Tibet. Pilgrims from all over flock to this temple to catch a glimpse of the Jowo Buddha, a statue that is said to have been blessed by the Buddha himself. Some pilgrims even prostrate all the way to the temple, even if it takes them years to travel from their home village to Lhasa. Others travel to the temple daily and prostrate in front of it, or circumambulate it while saying prayers.
