GSR is is measure of skin conductance. It varies by the amount of fluids on
the surface of the skin and the conductivity of those fluids. It correlates
fairly well with hormonal changes that cannot be perceived directly by the
individual. It's not the most accurate measure in the biofeedback toolbox,
but it is often helpful.
As for counting your heart-rate, that is a very primitive form of getting
feebback, but it has some disadvantages to measuring it mechanically. For
one, you have to pay attention to your heart rate to count it, which
rtestricts the level of attention you can pay to activities other than
counting. If you want to measure your heart rate while you are attending
closely to something else, you will want to use a mechanical method to do
so.
The goals of biofeedback are not exactly the same as the goals of yoga,
although they have some goals in common. I agree with you in that it is
stupid to think they are done with precisely the same intent.

There are lots of uses for these measures other than mapping one's spiritual
journeys. However, they can be used to measure some of the changes that the
practice of yoga or any other form of meditation will produce.
