There is something -- well, everything, really -- about that spiritual experience that is ineffable and eternally elusive. It's no wonder, then, that an integral part of virtually all major world faith traditions is music. It is the language of the soul, after all. What can't be said in words can certainly be expressed in melody and felt in rhythm.
HuffPost Religion has compiled here a series of photos and videos of timeless musical devotion. While this collection is woefully incomplete, it is intended to be an introduction to the world's major sacred music traditions, as well as a peek at some of the modern permutations of that spiritual practice. In the future, we hope to delve more deeply into the songs and sounds of specific faiths. But for now, enter the melody and see what is revealed.
