I happened to wake up the following two nights/early mornings after the meditation to not only feeling, but hearing quite a bit of energy going through my body. It sounded like what you said dayzero, electric. I had not had this happen to me in a while. So maybe, it is what you were told mudra, that our bodies would be filled with special energy during each of these meditations. Based on my experience dayzero, I say you're right about their being an awful lot of power to this meditation.
As for my experience during the meditation, it went good. I instantly felt the love coming from the group. At some point though, I was trying to send feelings of love, no violence and no destruction to our planet and felt a resistance. I was persistent, however, and whatever it was just felt like it gave up/surrendered. The remainder of the meditation I was just seeing swirling colors of green as well as white, feeling the connection with everyone and sending loving energies to our planet. Looking forward to the next one.
