"... Families facilitate the return of the souls to Earth by laying flower petals, candles and offerings along the path leading from the cemetery to their homes. The deceased’s favourite dishes are prepared and placed around the home shrine and the tomb alongside flowers and typical handicrafts, such as paper cut-outs. Great care is taken with all aspects of the preparations, for it is believed that the dead are capable of bringing prosperity (e.g. an abundant maize harvest) or misfortune (e.g. illness, accidents, financial difficulties) upon their families depending on how satisfactorily the rituals are executed. The dead are divided into several categories according to cause of death, age, sex and, in some cases, profession. A specific day of worship, determined by these categories, is designated for each deceased person. This encounter between the living and the dead affirms the role of the individual within society and contributes to reinforcing the political and social status of Mexico’s indigenous communities.
The Day of the Dead celebration holds great significance in the life of Mexico’s indigenous communities. The fusion of pre-Hispanic religious rites and Catholic feasts brings together two universes, one marked by indigenous belief systems, the other by worldviews introduced by the Europeans in the sixteenth century."
