She is now, in her own words, a philosophical Buddhist.
Does she actually practise Buddhist morality, meditation, repetition of mantras, reading of Buddhist scriptures? Does she acknowledge that the "self" is a delusion, that suffering arises from attachment and from attachment alone, that existence itself is suffering? If she doesn't do most or a combination of these things, she is not a Buddhist but just another person who thinks describing themself that way makes them more fashionable than the rest of us.
I tend to side with Father Seraphim Rose in believing that if she's a sincere Buddhist seeking the truth, it will be easier for her to eventually acknowledge the True God. If she's just another fashion "Buddhist", the journey will be longer and more painful.
Whatever the situation -- Lord, have mercy!
