there is a cermoney that they (a priest ) put some kind of ''magic'' inside the mouth
after they persurve the mummy for a couple of days
That was what he was associated with in Egypt.
The body was preserved, for the after-life.
Ceremonies such as Mummification, opening of the mouth (supposedly allowing mummies to talk, speak, hear, etc.) and gods such as, Anubis, god of mummification and embalming, and Osiris, god of the dead were often associated with Egyptian burial and death.
I'm not sure which culture's belief system you are referring to, quite a few employed mummification. In the ancient Egyptian pantheon, the god Anubis is most closely associated with mummification. Osiris, Isis and Nepthys are more loosely associated.
Wedding vows or cermonies.
no
The primary source for mummification is actual mummies and text references to how it was done at that time such as The Book of the Dead.http://www.spurlock.illinois.edu/exhibits/online/mummification/sources.html
Closing cermonies
I don't know of any, but Anubis the god of mummification has the head of a jackal.
It did not really have a name. It was the mummification process.
