Please. Let me join this discussion with few questions:

OK. We have a term called gut {I really dont know what the translation into my language is, but as i understood from your post, it seems to be the "force" which automatically constructs sensoric experience for me}. According to what i know about my attempts at visualisation, it really seem, that the one wanting to learn how to visualise must really understand, what are the rules under which visualisation works. As you brilliantly described, we should learn how to use our gut for our needs.

Please. Let me play with this word a little. For sake of making matters more concrete. Lets just imagine this gut as a person who provides me with images and sounds. Lets name him G. If we want to collaborate with G for our own purposes, we have to build some kind of communication interface. In real life, that would mean, that if I want to use services of G, i have to first understand him, give him some time so he opens and finding a way, how to tell him, what I want from him, without distracting him or being rude to him.

Lets say {hypotetically}, G was a person. My questions would be:
1. What should I avoid, when communicating with G?
2. How would G inform me, he is not satisfied with our collaboration?
3. What would G like as a present? What would make him happy?
4. Assuming, G is a very simple person and I really dont understand the language he speaks. What should be the words we should agree upon first?
5. Assuming, G loves freedom and doesnt want to be forced into collaboration, how would you persuate him?

I know, it might sound silly at first, but really if we make this abstraction, it really shifts the problem of visualisation into plane we are more accustomed to, the plane of human relations. I cannot really measure how much details i lost while performing this shift, yet. For me it is really important to find communication interface with my visualization faculty represented this or that way.
