During pranayama about a week ago, it started that I would get some automatic movements in the form of twitches in my right foot. This slowly progressed to more organised movement, which from time to time occured outside of practise.
Last night, however, this progressed to intense contraction of some muscles, for example pulling the little toe out and downwards until some ligaments in my foot went pop-pop-pop, and then the muscles release pop-pop-pop. It was if my foot was pulling itself apart and putting itself back toether again.
I should add it is completely painless, and my foot feels like it's had an amazingly intense massage. It actually feels that there would be more space between the bones in my foot, and I can feel a very pleasant coolness there.
I'm curious though, if this kind of exercise is desirable or not. It sounds like it could be put into the overload category, but at the same time, without this kind of stretching, I have no idea how I could have come up with the same result. In general, I have done very little in the way of asana practise, though I am changing that slowly. Am I at risk of damaging my foot, or other parts of the body, if this proceeds? Or is blind faith in Kundalini all that's required?
