Prayer flags are used in Tibetan Buddhism to spread messages and blessings through the wind. They typically feature images in the center surrounded by mantras or sutras. Tibetans hang strands of prayer flags in high-traffic outdoor areas to allow the wind to disperse the blessings. Originally painted by hand, woodblocks later allowed mass production of standard designs. Common symbols on prayer flags include the wind horse and eight auspicious symbols representing good fortune. People of any faith can create their own meaningful prayer flags using symbols and written prayers, wishes, or affirmations.
