What is a funeral?
It is an event about the death of a person connected to us.
What is the death of that person to us?
An unpleasant event.
Unpleasant, difficult, harsh things that happen to us (“the slings and arrows of life” that come our way, be them physical or emotional) are a house 6 matter.
Therefore a funeral is a house 6 matter. That is the essence of a funeral. There would not be a funeral had not that “bad” thing happened.
A ceremony, a celebration, a burial, a cremation, going to god, or going to hell, or meeting 88 virgins, are all secondary facets of the essential fact that a funeral is there because something not nice happened to someone related to us, that is: our friend, relative, whoever, died.
