The practice of hanging prayer flags goes back thousands of years to the Bon tradition which pre-dates Buddhism. It was a shamanic medicinal practice to help bring balance to the ancient elements that the colours of the flags represent. It is said that this balance can be achieved both internally, bringing health to mind and body, and externally by bringing harmony to the environment.  In fact the Tibetan word for prayer flags is Dar Cho, “Dar” means to increase life, fortune, health and wealth. “Cho” means all sentient beings. 
 
Paper prayer flags can be hung inside to increase harmony and spiritual awareness. It is important to treat prayer flags are treated with respect as they contain sacred text and symbols. When hanging the flags it is also important to have the correct intentions: “May all beings benefit” rather than something self-motivated: “I will benefit.”
