Tibetan Prayer Flags

Today I bought Tibetan Prayer flags for my room. They caught my eye and I thought the concept of wind blowing the flags resulting in blessings was so simplistic and beautiful that I decided to buy it. For more information on these prayer flags :-

Here is an excerpt:-
The Prayer Flag Tradition
To me there are few things more beautiful than colorful prayer flags fluttering in
the wind- sometimes waving gently, sometimes raging; a dance of shadow and
light. There is perhaps no simpler way to create good merit in this troubled world
of ours than to put prayer flags up for the benefit of other living beings. Prayer
flags are not just pretty pieces of colored cloth with funny writing on them. The
ancient Buddhist prayers, mantras and powerful symbols displayed on them
produce a spiritual vibration that is activated and carried by the wind across the
countryside. All beings that are touched by the wind are uplifted and a little
happier. The silent prayers are blessings spoken on the breath of nature. Just as
a drop of water can permeate the ocean, prayers dissolved in the wind extend to
fill all of space.
