The word Yoga is an Indian Sanskrit word meaning "to yoke" or "to unite." Unite what? Yoke what? Yoga is actually very well documented as being the practice of the Hindu religion. It is not Christian. Hinduism worships thousands and thousands of false gods. Perhaps even 33 million false gods in Hinduism! We know that when people unite with false gods, that they are being put under the yoke of Satan. When people do Yoga, they chant weird sounds and get into positions that you would see in India where people are doing the exact same positions in front of statues of false gods. While practicing Yoga there are long chants of "OM". The Hindu scriptures say that OM chanting is to connect everything in the universe which would include connection to all 33 million false gods also. "Everything in the universe" would include millions of demons, Satan and wicked people.
Our TRUE ONE GOD JESUS is the jealous GOD! That's what the bible says and teaches! If a female's husband sees her looking at another man or trying to be united with another man, or trying to come under another man's yoke, that husband will be very angry and jealous for a very good reason!
There's nothing wrong with normal exercise stretches. But when you add religious positions and sounds, you have entered into the demonic realm!
Even if a Yoga instructor teaches their own version of Yoga without the sounds, Jesus still hates it.
If the root is evil, then so is everything about it.
Yoga was invented by demonic pagan people as a form of demonic worship.
We can't take what is demonic and try to tame it down to nothing but just good exercises.
GOD sees the invisible.
GOD sees the roots, the origin and the underlying spirits/demons.
Evil is evil, and no matter how we change it, decorate it or edit it, it's still evil.
If we want to concentrate, then we can concentrate without Yoga. If we want to stretch, then we can do stretches without Yoga. We don't need any form of demonic worship to make us healthy. So Yoga is just totally unnecessary.
Yoga is in the spirit of "Coexist" and compromise with all forms of demonic worship.
