Prayer Flags in Darjeeling West Bengal

Trip to east India in April 2010, I found these interesting flags all over Himalayas and these looks so good and enhance the landscape at a different level.
A prayer flag is a colorful panel of rectangular cloth, often found strung along mountain ridges and peaks high in the Himalayas. They are used to bless the surrounding countryside and for other purposes. Prayer flags are believed to have originated with Bön, which predated Buddhism in Tibet.
