My wife wants to be a nun for 3 years

I have been doing TM meditation for almost 2 years and my wife has been doing it longer than that. My wife recently went to Vedanta academy in Pune for 2 weeks and she was told that meditation is no longer good and she said Vedanta is the answer for life. So she has given up meditation and she is now leaving for a 3 year course in the Vedanta academy. I have several questions but lets start with two questions- is meditation bad and is Vedanta really about leaving family and going away from your responsibilities.
