In my experience, I could be Buddha re-incarnate himself and still have a tough time dealing with her negativity.
My XW is a Buddhist, but not very devout like her mother. I suggested she speak to some monks nearby at a temple so as to try to get her mind and morals fixed. I was quite naive in thinking that monks, who have never been in a relationship, could talk any sense to her. However, maybe if I got the King of Thailand involved...
I wonder....was Yasodhara an LBS? I suppose that is a bit sacriligious because it might suggest that Buddha was going through a form of MLC during his journey for enlightenment.
As others have said, your W is going to have to come to her own awakening or answer. Pointing the path for her will just be percieved as controlling and she will resist.
