To obtain the Miraculous Virgin's favor, Vodou practitioners travel to the sacred Saut d’Eau waterfall to conduct a purification ritual. Most practitioners make the pilgrimage in summer, but the ritual is possible at any time of the year.
The ritual is called a "luck bath". The devotee journeys to the cult site with a calabash (a water flask made from a gourd) as well as gifts to offer to the goddess, before disrobing and diving under the magnificent Saut d'Eau waterfall. Devotees carry a small collection of leaves, plants, and herbs linked to the goddess and believed to have therapeutic virtues. If they want to, the supplicants can also bring orgeat syrup, perfume or flowers, or prepare a meal to offer as a pledge of their good faith and their loyalty to the lwa.
Once the preparations are complete, the supplicant bathes under the waterfall (either alone or with the help of an ougan (Vodou priest)), washing while invoking the protection and virtues of the goddess. It is critical, at the end of this ceremony, to break the calabash that served to carry water from the waterfall to wash oneself and to leave in the water the clothes which the supplicant had worn to the site - these represent their past bad luck. Instead, devotees leave dressed in new clothes, and hopefully imbued with the goddess' protection and luck for the future.
