Traditionally, prayer flags represent the five Feng Shui elements, water, metal, fire, wood and earth. Hang anywhere you want a concentration of supporting spiritual energy. If using indoors reposition them often as they need movement to be most effective. Tibetans believe the prayers and mantras will be blown by the wind to spread the good will and compassion into all pervading space. Individual flags are 6” x 7” with a length of cord at each end of the 7’ strand to tie it off.
