What is this electric feeling I have like an electric current passing through my body during meditation. It is like in the whole body or maybe not just in the body like in my sphere. It is a fine-tuned electric current that comes for a couple of seconds. It stops for a fraction of a second and there is nothing and then it starts again. It feels like it is changing direction. 
It is not unpleasant it just is. What is this? What can I do with it?
It may be piti, an emotion that can be aroused during meditation. 

It can also be a phenomenon accompanying meditation, since a lot of different unusual sensations can appear as a mere side effect.

...or it may be something else buddhism doesn't have a saying about. Meditation clears the path for a lot of things.
