It is a tradition in most western religions nowadays to bury the dead. This is a very unfortunate tradition as it harms the dead and it harms the living. The belief arose because of a misinterpretation of Jewish and Christian scripture, in which it is said that in a future age the messiah is going to come and raise the dead from their graves. People mistakenly took that literally and thought they had to prepare the physical body in a nice suit, ready to go to heaven. This is a misinterpretation. Unfortunately, it is the origin of many illnesses and sicknesses and a lot of black magic.

If you have a choice and you are serious in these types of studies, do not be buried, have your body cremated. Cremation annihilates and completely destroys all that physical matter, liberates all the energy from that matter, and quickly severs the connection to the personality so that the soul, the Consciousness, becomes free of those attachments and those bonds that draw the dead back to earth, to the physical level.
