In human cultures, it is common for the dead to be buried in large jars. The preferred method of burial (and the most expensive) separates the bones from the flesh. The bones are then placed in a large ceramic jar decorated with various writings. This jar is sealed with a wax and clay mixture that makes it watertight. The flesh is liquified and placed in a second sealed container. The second container is marked with a single glyph that represents the wheel of rebirth.
The bell of the bone jar is approximately four feet tall and about five feet in diameter at its widest point. It stands on four feet that are curious bound by chains near the feet. The feet are four different sizes, one extends into a three-foot diameter disk. The entire jar stands about five to five-and-a-half feet tall. The other jar, with the liquified entrails, sits on the large disk of the "odd" foot, placed upside-down.
This elaborate burial ceremony is intended to prevent the body from being animated by wizards or demons. Both wizards and demons seek to reanimate the whole body in an effect to gain the knowledge, spells and/or skills the deceased had when they were alive. Without both the bones and the flesh, wizards and demons cannot create the magical stones that would contain the deceased memories, knowledge and skills. (The truth is that these elaborate measures do little to deter wizards and demons.)
More importantly, it is intended to prevent ghosts to re-integrate with their bodies in an attempt to prevent their reincarnation. It is believed that if the ghost somehow manages to re-enter the bones, the shaking caused by its attempts to escape the bone jar will spill the contents of the second jar. It is believed that without the flesh, it is impossible for a ghost to re-enter their former bodies. This turns out to be true. There is such a great fear of a spirit re-entering its former body that the widespread reach of this custom has relegated the existence of a re-integrated body into myth and fairytale.
For those that cannot afford ceramic jars, clay jars are used instead. If the family of the deceased cannot afford jars with feet, the bone jar is made to sit flat on the ground. The liquified entrails are placed in a sealed metal box and buried in cement under the bone jar. Cement is very inexpensive, but cannot be made very thick. For this reason, to prevent a ghost from opening the second jar, it is buried at least three feet into the ground. Theoretically, it would be easier for a ghost to re-integrate into the body if the burial is done this way, however, the poor usually have little reason to avoid the wheel of rebirth.
