Only in a mosque.
Dreadful.
“Yoga originated with a blatantly anti-Christian philosophy, and that philosophy has not changed. It teaches one to focus on oneself instead of on the one true God. It encourages its participants to seek the answers to life’s difficult questions within their own consciousness instead of in the Word of God. It also leaves one open to deception from God’s enemy, who searches for victims whom he can turn away from God (1 Peter 5:8).”

At least it’s not a Clown Mass.
I think they are doing it on purpose, looking for an enlightened place for a pagan inspired routine ... and the hypocrites wouldn’t dare do it in a Muslim prayer room and would likely take their shoes off for a mosque.
Leaving aside the spiritual considerations, it just looks dang silly.
