A woman bathes in a trance of Saut d'eau pools to connect with Iwa. But if the dances and invocations have that emotional climax intrinsic to religion, is the sound of drums that actually dominates the landscape. This is where the state of trance-white eyes, involuntary movements, gestures-idem extends like a cloak psychotropic between 'ounsis'. There are few believers that go to Ville Bonheur just to look and end up dancing in muddy puddles to worship without being able to control neither his body nor his will, to the deities of the kingdom Dahomey (nor are few, indeed, those who understand nothing and assume this ceremony as pure theater.)
