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 those who are compelled to have a funeral?
An unpleasant event.
Unpleasant, difficult, painful, 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 ritual, 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 there a funeral because something not nice happened, that is: our friend, relative, whoever, died.
