Traditionally, prayer flags come in sets of five, one in each of five colors. The five colors represent the elements.
Traditionally, prayer flags are used to promote peace, compassion, strength, and wisdom. The flags do not carry prayers to 'gods,' a common misconception; rather, the Tibetans believe the prayers and mantras will be blown by the wind to spread the good will and compassion into all pervading space. Therefore, prayer flags are thought to bring benefit to all.
