Thank you everyone for your help. It really is helpful to read everyone else's interpretation of Master Lin's instructions. Iam2, your comment about the different layers is making sense to me - to go into the emptiness and connect to the universal energy first and then use the mind to direct the energy. KWLee, I have sometimes had the feeling that you described, that "the meditation will do itself", but wondered at the time if I had just lost focus - but then again, maybe the point is not to focus?? Maura, I think you have described part of my problem, that I'm trying to be too rational about this. I think what everyone is saying is to "relax" with all of this - something that I find difficult and probably one of the reasons why I decided to try qigong. Since it's impossible to "make" yourself relax, I guess it just takes practice.
I'm still wondering if others have found that they "struggled" before they were about to move forward or clear a major blockage?

Thanks again for all of your help. I'll do my best to follow your suggestions.
