This research proposes a psychoanalytic listening of the Malagasy bilo ritual in its classical form. The ritual’s function is to address the fertility issues of the entire lineage through the medium of the body of a woman described as “infertile” or who has only given birth to daughters. The goal is to fortify the life of a particular lineage, via a woman who will symbolically “give birth to” an ancestor. Our work aims to approach how the ritual accomplishes unconscious desires and processes psychic functions. We rely on the discourse of the work carried out by French anthropologists Fiéloux and Lombard who have studied the ritual most extensively. Five lines of analysis emerged: the central place of the body in the hallucinatory fulfilment of desire, the psychic treatment of femininity and passivity in both men and women, the processing of unconscious hostility, the elaboration of loss, and the projection of superego in the bilo.
