Anyone who sat through a knowledge session, came out the same person as they went in. Four rather badly explained meditation techniques were described but nothing was given. I believe we actually gave something in the knowledge session - I gave an orange if I remember rightly but nobody gave me anything.
The meditation techiniques and countless variations of them (some much better than Maharaji's) are to be found in your local library or even on the bookshelf at Sainsbury's. See the book, "Stress Relief For Women" and you'll find a very good explanation of breath meditation which is far simpler than Maharaji's technique.
Maharaji is just another person and is not God or a god but just a chancer. He had no idea that you even existed unless he knew you personally.
Yes I agree, people should stick together who've been through similar experiences. This forum is a good place for that and you'll find some really helpful people here.
