Burial or interment is the ritual act of placing a dead person or animal, sometimes with objects, into the ground. This is accomplished by excavating a pit or trench, placing the deceased and objects in it, and covering it over. Most would agree that humans have been burying their dead since shortly after the origin of the species.

The soul will continue on its journey to the next phase of its existence, whether or not the body is buried. If it were necessary for a body to be buried in order for the soul to progress, the earth would be packed with lost souls since so many people throughout time have died and have not had burials!
