Is it okay for a Christian to participate in a yoga exercise class or even see or become an acupuncturist?
It all depends on how you do it. Yoga, tai-chi, and some forms of holistic medicine can have a religious element to them, but they don’t have to. If a Christian takes yoga purely for the exercise, they are just fine (1 Tim 4:8), but if a Christian begins delving into the spiritual elements such as karma, Hinduism, etc. – that is wrong. There is only room for one God and one guide in our lives (2 Cor 6:16).
