In many religions of the world, collective prayers are often lifted in an audible form, but there is often a visual form as well. Candles are lit, altars are raised, monuments built. There’s something about seeing a physical representation of a person’s prayer that I find awe-inspiring. Tibetan Buddhists are no exception. They raise prayer flags in high spaces, streaming them across the mountainside, lifting prayers for others: for peace, for protection, for happiness. Seeing what must be hundreds of thousands of flags fluttering in the wind, knowing the many people they represent, is one of the most spectacular sites I have ever seen.
