I don't really understand the third verse though about "She". Any ideas?

He has a girlfriend/wife that he wants to keep for him to live in peace. She's the only reason why the man can keep calm.

I was wondering if some of the things in here are also referencing Mary perhaps? Kind of a cross between talking about his earthly mother, and Mary the Mother?
