Hi Shanti,
Not at all, there are no lifestyle changes at all, other than the practices which I've mentioned. In fact if there is one thing they do propose, it is to tread lightly along this journey, with a smile.
As with all of you, I too feel that dogma and blind practices would be a waste of this lifetime thats been given to us, to help us evolve...
I too have been searching with an open mind, and so far I haven't seen anything disappointing or jarring to the heart.
But I think it is best to focus more on the practices than the individual organizations, which is why I feel this website is such a wonderful medium!
Love,
