The five-colored prayer-flags can be impressive for those who have first been to Tibet. They are hung on peaks, mountain passes, or by roads and monasteries. They are also named because of the scripture on each flag. Blowing in the wind, they are also called sutra streamers.
To the believers, each waving of the flags means reciting the scripture once, sending wishes of sentient beings to the deities. In this way, the prayer-flags serve as a connection between the human beings and the deities. They also believe that deities are just behind the flags, listening to their prayers.
