People claim you can separate the practice from the religion but from what I’ve heard from practioners, is you can’t.
the yoga positions are prayer position indicating to the spirits a receptiveness to being invited in.
Stretching is great and I’m sure that in the past, and maybe even now, I’ve done stretching that is like yoga poses but never hold them and meditate while doing so.
Amen.
I don’t have anything concrete to add but during the 70s I had an in with a Southern California chain of yoga studios and was in a position to utilize everything for free at any of the coastal studios and of course the mostly female customer base, I forget the details, perhaps they wanted me in the business or something since I had met and become friends with the owners and highest mgmt, it was all a very cool thing for me but I was suspicious of yoga and had to learn more about it before participating.
Yoga was very big in California at time and I did a deep look into it to see how it fit in with my being a Christian and while there were many shallow ways to look at it as just an exercise activity, a deeper look always led to the fact that there was more to it, an unchristian spiritual aspect, again, I don’t remember the details but I did decide that there was just no way I could participate although I would have liked to find out that it was as benign as some claim and of course there were many people trying to persuade me of how harmless it was with good arguments, but they wouldn’t hold up to close examination from the Christian perspective.
