I'm no expert, but it sounds to me like what you are experiencing is termed "success."
In my humble opinion that burning you feel is the clearing of a path between the two poles of your divided consciousness.
Someone once induced a sensation in my lumber spinal region, a sensation I would describe much as you've described this heat you're feeling. Below the lumbar, I was already "clear."
If you ever get a chance to experience that "heat" (if you examine it thoroughly, I think you'll find that it's really vibratory in nature)extending all the way from your perineum to your brain, do nothing. Let it happen.
If you're extremely lucky, you'll cease being two conflicting minds at opposite ends of your own spinal coloumn.
Anyway, that's the opinion of some jerk on a BBS.
