i respect your Christian P.O.V. and in no way am trying to debate you.
That said, i'd like to point out that Kundalini and Kali is two different things. Kali= Hindu Goddess, associated with Death, but suffice to say, not
kundalini.
Kundalini isn't really a serpent in the body at the base of the spine. That is metaphorical and used as a desriptor to make it easier to meditate. i
personally never used it even as a beginner. Its not necessary.
What is viewed as demon possession is not from kundalini meditation, as that is shutting oneself within the confines of ones own mind, and does not
allow outside interference.
What demon possession is, is most likely negative entities invading ones mind/spirit/body. This could come from all the negativity surrounding your
relatives life. These negative entities gravitate towards people whose lives are filled with negativity. They very well could have been there for
awhile.
My suggestion is to ask her if she is into occult, which meditation is not apart of nor have anything to do with. Ask her if she has been involved in
any occult rituals, or seances. This would open portal, so to speak, for the neg. polarity entities to enter within her. That said, it could be demon
possession if that is the case.
i would like to further stress the fact that Kundalin Meditation has nothing to do with the occult, nor does it allow for outside influences to
disturb or enter the mind/body. Just the opposite. Occult = Outside Forces Meditation= Innate Human Psychic abilities. We all got them.
From a physical standpoint, stress is a big factor in unexplained pains in the body. This is triggered when the brain gets too much of a certain
chemical and sends it to an extremity of the body. My suggestion for this, though wether or not you take it , i dunno, is Meditation.
i know,
but seriously, it reduces stress like you wouldn't believe. Well, unless you try it.
Good luck.
Love and Peace
