Nope. Not even close. The Ashram where I used to do yoga did have a community worship gathering where the curtain with a statue of Gansesh was kept was opened, but worship of the icon was not part of practice. Absolutely zero of the Asanas had to do with any Hindu dieties. The closest thing was the Sleep of the Gods, which was essentially a relaxation technique that is similar to most forms of self-hypnosis. Yoga is about marrying physical, mental, and spiritual control. It is about health and wholeness. Unless you believe there actually are Hindu gods rather than their being architypes for aspects of human personality, there is no cause for concern. Such a belief would be superstition on your-part, by the way, or sadly on Bishop Naumann’s part, showing he is a true idiot or is pandering to the fears of his Trad flock, which is even worse.
