If you call any of the folks involved in these organizations, I'm pretty sure they'd be helpful and give you an idea of what would be best for you. People travel quite far to do the program I'm in. It's very enjoyable and the company is excellent. I think a course is probably much more beneficial than studying on one's own. It makes otherwise dense and abstract information more relatable, and allows one to not only see the processes in action, but also to meet and get to know admirable grounded people who have committed much of their lives to Biodynamics and know its rewards well. Way cool!
