Cremation and The Holocaust

In your column of Dec 31st, you explained the importance of burial vs cremation, with respect to the Jewish belief in the Revival of the Dead, the final reward when the body is reunited with the soul, something which may be lost on one who forfeits the body to cremation.
Unfortunately, there are so many of us eternally mourning all the victims of the Nazis, whose bodies were cremated en mass by no choice of their own. How does Judaism deal with those martyrs who never had a choice with respect to the final reward you discussed?

Cremation or Burial

My mother was recently put into hospice and for the first time she’s facing death as a reality. We’ve been discussing burial and her desire, and she has been leaning towards cremation so not to put any financial burden on our family. Something feels wrong to me about that; to me it’s worth a financial stretch to have her buried the traditional way, but I wanted to know if Jewish law is ok with cremation or is there a real reason to prefer burial?

Cremation

As my mother has gotten older she has expressed a desire to be cremated. I have spoken to her about this and reminded her that she couldn’t be interred in a ‘Jewish’ cemetery (And asked her if 6 million Jews being burned wasn’t enough). She has resisted my arguments. I fear that if she dies, I won’t be able to attend her funeral. I could use some help here.
