The veneration of ancestors has led to the widespread tradition of tomb building, as well as the highlands practice of the "famadihana", whereby a deceased family member's remains are exhumed and re-wrapped in fresh silk shrouds, before being replaced in the tomb. The "famadihana" is an occasion to celebrate the beloved ancestor's memory, reunite with family and community, and enjoy a festive atmosphere. Residents of surrounding villages are often invited to attend the party, where food and rum are typically served, and a "hiragasy" troupe or other musical entertainment is commonly present. Consideration for ancestors is also demonstrated through adherence to "fady", taboos that are respected during and after the lifetime of the person who establishes them. It is widely believed that by showing respect for ancestors in these ways, they may intervene on behalf of the living. Conversely, misfortunes are often attributed to ancestors whose memory or wishes have been neglected. The sacrifice of zebu is a traditional method used to appease or honor the ancestors. In addition, the Malagasy traditionally believe in a creator god, called Zanahary or Andriamanitra.
