The majority of people in Poland expect to be buried (after they die of course), with cremation being a minority aspiration. My own prejudice is against the messy rotting in the ground, much preferring a quick clean disposal.
Even ashes used to have to be placed in cemeteries, but changes to this were discussed some years ago. I never heard any more, but an article in Dziennik.pl confirms this is still a requirement. In England, my mother Mother had her ashes scattered on the crematorium roses and my final resting place being the garden is fine by me. Not possible here though.
I do go to family graves as a rather bemused assistant, but I can't help think that simply stepping out the door to visit me would be more convenient. Its not something I believe in, but if I wake up some day for whatever reason Roman Catholics have, I'd be interested to see what happened to the garden.
The garden a week ago, with snow.
