I found the “Surround Sound” practice to be very stimulating, but still very clear and calming. I have a spot in the woods with a fire-pit and hammock that’s kind of its own corner of the world. Practicing with eyes closed helped me realize just how far my senses and awareness could reach.
In a lot of ways I felt like the line between what I could hear in the distance, and where I physically sat was kind of blurred.
When my eyes were open, I realized I had to reestablish my focus pretty frequently, but I also found that this field of awareness around me was more like a dialogue between my senses and the rest of nature that was going on around me.
It was a very grounding exercise, that I will definitely keep practicing.
