Yeah I did some research after it happened and it definitely sounded like a kundalini yoga type experience. It happened randomly, and has happened other times as well but they are sporadic. I meditate relatively often but cant force the energy experience. I don't know why it happens sometimes but not others. The experience almost always happens in my head though i have heard that it can happen at any of the chakra points. I once had a very brief sensation in my throat but its harder to describe. It was like energy circling in that area.

Anyway, thanks for the comment. I will check out your blog :)
