"The heart of man has been constituted by the Almighty that, like a flint, it contains a hidden fire which is evoked by music and harmony and renders man beside himself with ecstasy. These harmonies are echoes of that higher world of beauty which we call the world of spirits; they remind man of his relationship with that world and produce in him an emotion so deep and strange that he himself is powerless to explain it. The effects of music and dancing fan into a flame whatever love is already dormant in the heart, wether it be earthly and sensual, or divine and spiritual."

Imam Ghazzali continues that "pure religious music is used by the Sufis to stir up in themselves greater love toward God often obtaining spiritual visions and ecstasies, their heart becoming as clean as silver in the flame of a furnace."
