Thank you,
Yes Vipssana is very effective... there are free retreat centres all over the world, it starts with a 10 day intense retreat... I haven't done it yet but am trying to integrate the philosophy into my daily life of observing my thoughts and emotions rather than react to them.
There is a really good documentary here where they introduce Vipassana into an Indian prison... check it out when you have time!

Thank you for reading!!
