Hello Jordan,
It seems that in this expression the visualization can be somewhat different each time you "embrace the universe." It is after all a pretty big place

. Some of the other long time instructors may have more to say, but you might imagine almost your arms reaching out to all the universe. I suppose that not being too rigid with the visualization is the best posture, "kind-hearted, peaceful mood, broad-minded." That way, what can come, will come. Hope that satisfies, we are all learning.
