Gotcha. My warmest thanks, Rawn :-) <<without the emotions, images and thoughts that are naturally involved with a memory>> A last naïve question, if I may : so this means that instead of focusing upon a *sensation* at the *astral* level (since it contains emotions etc.), I'm focusing upon a *perception* at a *mental* level or higher ? Sorry to be so complicated, but I have the feeling I won't derive all possible benefit from this exercise if I don't know what body I'm working with :-) Once I can focus long enough on the sensation, and independently of this exercise, I'll use cold to play a little game "à la Archaeous levels 1 to 3", to watch the impacts upon the various levels and bodies of a known and isolated stimulus. May be interesting :-) Thanks again. NB > The sensations of cold arise from your cognition or perception of > the essential meaning of coldness.
