I am not sure but this might be the reason.
For some reason or the other her solar plexus chakra might have been stimulated and must have started taking in and giving off energy in large quantities. Thus large amount of energy movement might have produced the magnetic pull sensation as felt while making Ki Balls.
hi im josemi from spain. i have a friend who has a doubt. this has happened to her: she was after the nap, she got up and laid down again. she got very relaxed, she had a hand over the solar plexus (the stomach) she felt as though the hand wanted to penetrate in it, at the same time the solar plexus atracted itself, like a magnet compressing itself. she wants to know if this has something to do with the chakras or whatever. she travels astral sometimes. thanks.
