seriously, i've never understood spending so much money on rituals like burial or marriage, might as well set it on fire. i'd just do aquamation or mushroom burial, whichever's the best mix of green/cheap.
It's a way of dealing with the fear of death. "When I die, an event will be organized for me and then I'll go to heaven". The living need to do that to maintain the illusion.
I mean, I understand their motivations at a distance, but I've always tried to confront harsh realities including my own mortality. It seems the better option to me over dulling the sensation with stupefiants or belief systems.
