And The Answer Is Blowing In The Wind
These are some of the prayer flags flapping in the wind bringing with them the auspicious mantras to clear obstacles. I always love looking at the prayer flags at home seeing them flapping in the wind.
"Stringing Buddhist Prayer Flags is thought to be beneficial for all beings in the immediate area, and to benefit the karma of the individual who hangs the flags. Prayer flags will deteriorate from time spent out in the elements, so they are typically renewed each Tibetan new year by pilgrams visiting sacred sites. The old flags are not removed, the new flags are simply added to the existing prayers. These sites eventually build into wonderful displays of prayers and colors - mouseover the above photo to see such a site on a high mountain pass in Tibet."
