Do you have any information on these sensations? When this particular meditation is "working" (or at least, when I believe it is), I feel kind of a tingling over my whole body that I don't feel in any other circumstance, I don't know how better to describe it. It's usually around the part where the guided meditation says something like "try to find the rhythm beneath your heart rhythm" FWIW the guided meditation that got me to my "experience" was apparently inspired by Babaji
