Hello all, I need some explanation from you about something that happens to me since I was a little boy.
It's very simple, when I was a child, sometimes I had a feel of a consistent sensation of "energy" flowing up through the entire width of my vertebral column (is this the english for "colonna vertebrale"?

), it was something like a thrill sensation, but it was not unpleasant anyway.
Through the time, playing with this strange phenomenon to find how to have control on it, because it was really interesting to me, I learned how to make this phenomenon appear at my will, simply desiring for this "energy" to flow and "pulling" this "energy" from the base of my vertebral column.
My question is: what is that? Is it really energy? Is it harmful?
I never cared too much about this "funny" phenomenon, but now that I'm approaching with spiritual things, I'm searching for answers, and I know that this is a good place for searching

Thanks in advance to all who will reply!
Bye
