Stuck

So I need some advise from all you LDS lovin pals. I have mentioned before my friend, Maria from Philadelphia. Well, she actually passed away last year while we were there. Long and unlucky story, she went to the ER the day she came home from visiting me in Utah, and I didn't find out until I was in Philly after our cruise, and she passed away about an hour later so I didn't even have a chance to visit her. It was a really sad time for me.

Her funeral was very different than anything I had ever experienced. It was not quiet, and not very focused on Maria. It was actually a little difficult for me to sit through the whole thing.

Anyway, now it has been over a year since she passed away. On the 1 year anniversary of her passing, I called her mom to see how she was doing. After talking for a while, I told her a little bit about what I believe about baptism as a member of the LDS church, and wanted to know if I could have permission to do ordinaces for Maria in the temple. Her mom said she was confused about what I believe, and had let the missionaries come over a few times after Maria passed but didn't want them to come back right now to teach her more about it. I don't know what to do or how to explain to her why this is so important to me. Is there a good article or anything out there that explains why it is so important for us? Maria was baptized when she was 12, so her mom doesn't understand why and/or how I could do it again for her. I have been wondering and worrying about this for a while now, and I know the longer I wait the harder it will be. She sounds like she just doesn't understand why I would want to do it. Maybe if she could then she would let me.....
