Prayer flags come in sets of five colors, blue, white, red, green, and yellow, that correspond with the 5 Elements, Blue symbolizes the sky and space, white symbolizes the air and wind, red symbolizes fire, green symbolizes water, and yellow symbolizes earth. According to Traditional Tibetan medicine, health and harmony are produced through the balance of the five elements.
Prayer flags are flown on auspicious days for different reasons including the removal of obstacles or illness; protection against harm when traveling; and on important occasions like marriages, and other official functions.
Traditionally, prayer flags are used to promote peace, compassion, strength, and wisdom. The Tibetans believe the prayers and mantras will be blown by the wind to spread goodwill and compassion into all pervading space. Therefore, prayer flags are thought to bring benefit to all.
There are 15 flags in one set.
