How do I convince my mum to not pray so much and not to give away 10% of her income to the church ? I have no problem with her praying, but she's prays like every two-three hours (she wakes up in the middle of the night to pray). Sometimes she burns food because of it, once she passed her train station stop and she prays every time before she has to drive ( she's one of those people who thanks god when she finds a parking space). My dad says praying too much is making her luny. She prays so much she can make a nun look like an atheist.  

Also she gives way too much of her hard owned cash to the church (she feels like all the good things that have happened to her is because she joined that church). I told her she should give it to a charity instead, doesn't listen. A big portion goes to the person who has preached that day (I recall a preacher saying more $$$=more blessings). The money also goes to a guy overseas who founded the ministry, who is a millionaire anyways.
