Is doing yoga evil? Doesn't it lead to getting involved with demonic things?
No, yoga is not inherently evil. Practicing yoga is not an occult activity, and it does not necessarily lead one into involvement with the diabolical. Yoga is a non-Christian Eastern spiritual practice that involves bodily postures, breathing exercises, and meditation and Christians should not pursue it as a spiritual path. That said, the bodily postures and breathing exercises common to yoga may be used by Christians for non-spiritual exercise. For more information, I recommend an article I wrote, The Trouble with Yoga.
