Or maybe not...
I'm not an expert on what will or wont get you closer to St. Peter in the afterlife, but personally, I think those who tell their parishioners that they shouldn't practice yoga because it diverges from Christian values are off-base.
There are plenty of totems that have been "normalized" from an Eastern culture - yoga being one of them. Heck modern-day Christianity stems from a multi-god religion. Yes, yoga is a Buddhist practice used to achieve a oneness with the universe and depending on your type of yogi - you may or may not chant. So what! If you don't like chanting, turn it into Hail Mary's or other prayers.
Honestly, if you ask many Americans why they take yoga, it's for health benefits - it's a good work, it helps center Type A personalities after stressful days through the use of concentrated breathing and stretching movements. I don't think practicing yoga in the US negates your Christian values. If anything, a Christian may use their yoga time to meditate and say private prayers.
The day people stop spreading hate and start learning about the subtle differences among us - we will all be a better person for it.
