Learning of Kundalini Yoga
I finally forced myself to say a little bit about the vibrations to my yoga instructor. (Okay, okay, I admit, I stalked her, following her to her car so I could ask her this privately.) She mentioned that there is this concept in Yoga called Kundalini, and perhaps that's what I'm experiencing.
It's late in the evening, but I'm off to the bookstore one more time, sweatpants and all. :)
