What are some examples of events in the book that showed the centrality of vodou in the daily lives of the slaves, and the role that it played for them in the Haitian revolution?

In Part II, the gathered slaves call out to the voodoo gods for help, and they sacrifice a pig with a machete, adorning themselves with blood. Their rebellion is planned for eight days hence, and the Africans hope for help from the Spanish colonies.

In context, the people are certain that their rebellion is supported by the Loas, the gods of voodoo. They make their sacrifices to the gods, and thus, their pacts are formalized. Though the gods are created in the minds of the men, the power of the pacts becomes real in the motivation to fight and the belief that victory is possible.
