Prayer flags above the town and district center of Wangdi Phodrang. Buddhist prayers are imprinted onto flags that are attached to tall hand hewn poles. The prayers are said to disperse into the winds for the protection of people living or dead. Some are wind flags, which are erected on mountaintops and hillsides for personal wishes on behalf of the erector. Others are prayer flags, which are erected by families to cleanse the sins of their deceased family members. From coverage of revisit to Material World Project family in Bhutan, 2001.
