My friends have the feeling that yoga is some type of anti-religious activity.I find it to be excellent exercise and a pure and good way to stretch and relax. Have you ever heard of yoga being negative as a Christian activity?
Garden variety Yoga exercises for stretching and toning muscles such as you might find at a health club are probably harmless. It’s the religion behind it that’s troublesome. When you begin meditating or focusing on the god within or trying to enter into a state of total relaxation to connect with your higher self you are practicing the Hindu religion whose beliefs are incompatible with Christianity. At best it’s pagan and at worst it’s occultic. It’s been said that in effect every Yoga instructor is a missionary for Hinduism. Be very careful.
