Faune,
I went to the website you gave and it did sound very interesting. I read and read and read. I also looked into the cost of what it would take to go to India for their 21 day program and it would cost minimally $10,000. Well, from where I am coming from that was not a possibility at least now. Yet I continued to read because it intrigued me. I followed one of their links to the What the Bleep website to read an objective view of it all. What I found was very encouraging. It seems a European doctor began studying this and found that the brain did indeed show notable differences in the left sphere. Also he found the part of the brain that is behind pure joy was immensly enlarged. ( please forgive me if I am not relaying this exactly right as I am doing so from a congested memory.) On the What the Bleep website I found a link to Ron Roth. I was not familiar with him but am so glad I found him. He goes to India once a year to deepen himself, he works in connection with John of God , and best of all he delivers deeksha and resides in the good old USA. His story, manner, and accessibility intrigued me as he is much like Joel Goldsmith whom I studied for several years. He resides in Illinois and if that's too far he does do telephone deeksha. On a final note in an explanation of his last intensive, they had a demonstration of the ancient art of qigong. I am most thankful to you Faune for this great info.
God bless
