I just need to inform you not trying to attack anyone that our creator God doesn't want us to do yoga because when we are doing yoga we are open to some other spirits that are not from God.
1 Timothy 4:1 The Spirit says clearly that in later times some believers will desert the Christian faith. They will follow spirits that deceive, and they will believe the teachings of demons.

1 John 4:1 Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
