Self Mummification

For a little less than three years the priests would eat a special diet consisting only of nuts and seeds, while taking part in a regimen of rigorous physical activity that stripped them of their body fat. They then ate only bark and roots of pine trees for another three years and began drinking a poisonous tea made from the sap of the Urushi tree. This caused vomiting and a rapid loss of bodily fluids, and most importantly, it made the body too poisonous to be eaten by maggots. Finally, a self-mummifying monk would lock himself in a stone tomb barely larger than his body, where he would not move from the lotus position. His only connection to the outside world was an air tube and a bell. Each day he rang a bell to let those outside know that he was still alive.
When the bell stopped ringing, the tube was removed and the tomb sealed. After the tomb was sealed, the other monks in the temple would wait another three years, and open the tomb to see if the mummification was successful.
If the monk had been successfully mummified, they were immediately seen as a Buddha and put in the temple for viewing. Usually, though, there was just a decomposed body. Although they were not viewed as a true Buddha if they were not mummified, they were still admired and revered for their dedication and spirit.
 It is believed that many hundreds of monks tried, but only between 16 and 24 such mummifications have been discovered to date.

Mummies from other Civilizations

Besides the Egyptian and the Inca Civilizations you may be surprised that several others also practiced this form of burial, by both natural and through the practice.  Natural mummies have been found in Italy, North America, and Russia due to the extreme cold that preserves the body. Another form of natural mummification occurs when a person dies and falls into a  sphagnum bog, the acidity of the water, cold temperature and lack of oxygen combined to tan the body's skin and soft tissues and preserve the body. These have been found in many locations, Europe seems to be a popular location to find these mummies. A tribe called Guanches, from the Canary Islands, practiced a form of embalming their dead and therefore helped the bodies withstand time and become mummified. Chinchorro mummies are the oldest mummies known, these were mostly accidental in the beginning as bodies were placed in the dry wastelands they became completely dried and preserved.  The Chinchorro tribe are found in South America in Chile and Peru. In China mummies have been found, with complete bodies and organs.

Some claim that some Buddhist monks, buried themselves and through meditation and slow starvation and suffocation, their bodies have been recovered with very little damage.  Most were buried with several drying agents and prior to their death the monks stuck to a sparse diet made up of salt, nuts, seeds, roots, pine bark, and urushi tea.

The Basic Life as an Inca Mummy

 The Inca empire consisted of a central government with the Inca at its head and four provincial governments with strong leaders: Chinchasuyu (NW), Antisuyu (NE), Contisuyu (SW), and Collasuyu (SE). At its height, the Inca Empire included Peru and Bolivia, most of what is now Ecuador, a large portion of what is today Chile north of Maule River. The empire also extended into corners of Argentina and Colombia. However, most of the southern portion of the Inca empire, the portion denominated as Collasuyu, was desert wasteland.

At the top of Inca society was the emperor, the Sapa Inca. The Incas believed their ruler was descended from the sun god and he was treated with great respect. Below the Sapa Inca were the nobles. Below them were a class of men called curacas. They were not necessarily Incas. When the Incas conquered a people they took the leader's sons and taught them to rule the Inca way. They then became curacas. At the bottom of Inca society were the craftsmen and farmers.

The Inca ruler and the mummies of his predecessors were the most important religious leaders. They were assisted by a hierarchical priesthood headed by the high priest of the Coricancha. Important shrines also had staffs of female attendants who wove cloth and brewed chicha (maize beer) for use in festivals. Most ceremonies involved sacrifices of cloth, chicha, plants, or animals. Important Incas were mummified and typically buried in their finery amid rare objects and provisions that would be needed for the journey to the afterlife. Their long list of burial possessions even included, on some occasions, sacrificed humans. An elaborate ritual life surrounded the mummies of deceased rulers, who were treated as if they were still alive. They were maintained in state in their palaces, and they continued to own the property they had accumulated during their lifetimes. Their descendants managed the mummies' property for them, consulted them as oracles (bearers of messages from the gods), made sacrifices to them, ate and drank with them, took them to visit one another, and brought them out of their palaces to participate in major ceremonies. During important festivals, the royal bundles were moved from their places of rest, and dressed up in the finest garments available in order to attend the festival. The dead also sat in on important meetings and functions, but in all cases were treated with the utmost respect.

The Incas believed that their dead ancestors governed various aspects of their lives, and for this and other reasons were worthy of being worshiped. The bodies of dead rulers were among the holiest shrines in the empire.
 

The mummy bundles served many purposes to the Inca, not only did they provide a strong heritage and history, they also became a link to strengthening power relations.  They still had the remains and could trace the connection of kings all the way back to the first Inca Manco Capac. Incas created songs of each of the deceased lords in order to remember them and their time as king, after each successor a new phrase was added to remember.
