I not sure, but i think the purpose of Buddhist funeral is for
family to accumulate merits for the deceased... like ask monks to
come and do prayers, make offerings, put food out for the deceased
etc.
Buddhist funeral shd not have mahjong/cards/mourning....
haha
I think its just to lead the soul/spirit to the other world, or
something. Mahjong/cards all those i think is just to attract
people to the funeral place, as some elderly people prefer Re nao.
If you know what i mean.
