Relaxation and substances

Class today was very interesting to say the least. It took me a while to focus, to really concentrate on breathing and just being still. However, once I was able to focus, I was totally relaxed and was able to visualize what was going on. When I stood up and opened my eyes, it was much harder to still see the substance; but I think that was just because I hit the boundary of my comfort zone. I was surprised that I was able to relax so much, because I am the type of person that is always worried about stuff. I am very interested to see where this exercise goes on Thursday. I haven't yet figured out the reason for the exercise, but not knowing will drive me crazy.
