Hi David! That could be one way to describe the chills, but I wouldn’t use the word ‘firework’ — it’s more like an energy center sending waves out from my heart area to the rest of my body, I wouldn’t say it’s totally dramatic though, like it wouldn’t stop me from doing anything else. But it sounds similar. Since writing this piece, they’ve died down for me and I have changed my views slightly to thinking maybe they are my higher self kind of giving me a hug. Anyway, they are definitely something powerful that comes from my heart chakra area, and that means something about love and universal understanding. I just take them as a good and comforting sign. Also, they could be a sign of our own energetic power — that scientists of course would have us disbelieve. I mean we do know that the heart has an electromagnetic field in science, but can it send reverberations of energy and love? I say yes.
