Hello! If I wish to do traditional witchcraft, can I work with the deceased?
I think maybe anon was hunting for the word they wanted. I am going to take this to mean ancestors and spirits of the dead. And the answer is yes, traditional witchcraft as a general rule does interact with spirits of the dead.
Most often seekers begin with either a solemn visit to the graveyard where they begin tending a grave before eventually opening up to communications. Some even seek initiation by sleeping on a grave. (Be aware of your local laws and take care in choosing an appropriate grave).
Or even more popular a method is to create an ancestor altar of photos and artifacts of your relatives and culture. Adopted seekers may choose to begin with their adopted family’s line, since they are bonded to that line by contract and love if not by blood. Another option to do instead or in concert with the above is a witch ancestor altar with images of witches and cunningfolk of the past you wish to connect with.
If you meant another kind of deceased let me know.
