Tibetan Prayer Flags. Set of 10 Prayer Flags each measuring 17cm x 19cm. Prayer flags are inscribed with auspicious symbols, invocations, prayers, and mantras. Tibetan Buddhists for centuries have planted these flags outside their homes and places of spiritual practice for the wind to carry the beneficent vibrations across the countryside. Prayer flags are said to bring happiness, long life and prosperity to the flag planter and those in the vicinity. The five colours of yellow, green, red, white and blue represent the elements: earth, water, fire, cloud, sky.
