Whaaaaat? I never heard of yoga at all in relation to anything but yoga class.
Sure I go to Yoga class, and um, Hindi religion never even crossed my mind. I don’t even think there is a Hindu in the class, but either way, that’s just going too far!
That’s like saying (if you are not Christian) your kids can’t hunt for eggs at Easter because then it’s a Christian religious practice.
But I never heard anyone of any religion mention things as Satanic. Maybe when pondering the Holocaust I’ve heard people mention evil and the devil?
It depends on the type of yoga.
It’s not about being against different cultures, its not about being against exercise, although perhaps to some extent whether or not it is Christian (though not in a cultural sense but rather in the source of certain “powers”), but more about the nature of the thing.
Some yoga is more like exercise, but what about the type where people promote having out of body experiences or getting in touch with your third eye or the chakras? What is the source of these preternatural experiences?
What about the popular practices described in the book “The Secret” or other similar books which describe making things happen by way of manipulation with your mind or your “vibrations”? What about the use of crystals to enhance these “powers”?
What about reiki? What is the source of this miraculous “healing” or “warming sensation”?
Some claim it is nature. Some claim it is God. Some claim the power is within you.
When one meditates, if the aim is to “empty the mind”, what then fills it?
There is a reason you find related books in the isle called “New Age” - i.e. what some also refer to as the “post Christian age”.
All that aside - the people who should know, that is, exorcists who regularly encounter the demonic, often indicate the source of these “powers” are not natural and not from God. You can do the math. There is a fine line here. Use caution.
