Yoga is not evil nor of the devil.
If people want to believe that, that’s their free choice.
Also, Hinduism is not of the devil.
There is one God, not many. Some people worship Him one way, some slightly differently. Hating those of other religions (not counting Islam, as they want to kill us all) is not a way to serve God.
Ugh. Where's Headache Guy when you need him?
