So the first time I tried envisioning my container it was a bit hard, but then the second time I was able to do it when we were to create a ball of light. It was a wonderful experience which led me to realize that my container is my actual body.
So with each meditation this week I used my body as a visualization of my container. Actually my mind went straight away to this vision because it already encompassed it in the meditation prior.
Maybe I will get better at envisioning a container in front of me, either way it works for me.
What I found amazing was watching future self in a screen before me. Each time I did this meditation it took my story further and further into detail and gave me amazing insight to a future I could not have just imagined. I was blown away by what I saw. The thing is, I can actually see this future as being extremely possible!
