This is an interesting thread! I was raised by born again Christians, my Dad is a vicar and very against some of the things I'm into.
For example, meditation. When i first learnt Transcendental Meditation a few years ago, their belief was that it was against Christianity because you're given a mantra and that it was the name of a hindu God and therefore you are praying to someone other than Jesus.
When I learnt Vipassana, where there is no mantra..and you focus on your breath and body sensations, I was told that this was "bad" because it leaves your mind so open that it allows for "evil" spirits to enter.
I can see why, as a Christian, they would be against some of the moves in Indian head massage. Its not my belief personally, but I know what theirs are..having grown up with it and to them, it is very much the "occult" in a lot of cases. Healing, energy, chakras, meditation, its something most Christians, especially born again ones, will stay away from.
I said to my Dad that if anyone can o harm with their body using their body then the fault must surely lie with the manufacturer, not the person! Of course it seems insane that you are doing "wrong" by meditating when you are essentially experiencing your Self in its truest form!
