of life's changes and an acknowledgment that all beings are part of a greater ongoing cycle. According to traditional belief, because the symbols and mantras on prayer flags are sacred, they should be treated with respect. They should not be placed on the ground or used on clothing. Old prayer flags should be burned. Timing of hanging and taking down Some believe that if the flags are hung on inauspicious astrological dates, they may bring negative results for as long as they are flying. The best time to put up new prayer flags is in the morning on sunny, windy days. In Tibet, old prayer flags are replaced with new ones annually on the Tibetan New Year.
