Thanks Thomas for the suggestions. Yes we did all that and more and problem solved. Where would we be without our priests and the Church? Yes, and I think that's true for most Christians too. I shared the point-of-view that it's harmless a few years ago, but when I looked into it, I found out how the postures themselves are inseparable from the context of Hinduism in which Yoga is rooted, which makes it not-so-harmless!
