Towering high above the center of this ancient city, the Shwedagon Pagoda is one of the great wonders of the religious world. Said to be encased in more than sixty tons of gold, the Shwedagon is older than the city itself. Its earliest legend goes back 2,500 years, when two brothers from lower Burma are said to have met the Buddha shortly after his Enlightenment. As proof of their friendship, the Buddha plucked eight strands of hair from his head, which they brought back and enshrined within the Shwedagon. There it remains, alongside the Buddha's famous precepts, the first of which reads: "Avoid killing, or harming any living thing."
