Dear NB, >> a) Is there any meaning to the fact that I have less problems focusing and visualizing with open eyes than with closed eyes ? This is new btw; in the past, it was the opposite. << I also have an easier time with my eyes open. Of course, if you've only tried "eyes open" after "eyes closed" then it should be a bit easier. Although, I've found that it is easier for me even without first starting with the eyes closed. As far as I know, there is no real significance to this. >> b) Is the instruction "start with closed eyes and redo with open eyes" mandatory or is it just a trick because working with closed eyes is supposed to be easier as a first step e.g.? << Working with eyes open and closed is mandatory and necessary. But the order isn't so much important. You could just as well start with "eyes open" and then move to "eyes closed". All Will Go Well, --Alan
