Yoga is an ancient practice with its roots in Hinduism. It originated over 5,000 years ago in northern India, but for many, has now evolved from a spiritual path into the wellness practice known globally. In the West, millions now do yoga as a form of exercise and wellbeing. It is an industry thought to be worth tens of billions of dollars. But as it has boomed, yoga has been interpreted in new and sometimes controversial ways. What has been dubbed 'Christian yoga' has gained loyal supporters, who say it helps them reconnect body and soul. But not everyone agrees. Some within the Hindu faith argue that Christian yoga risks stripping an ancient practice of its religious roots. Then, there are Christians who say the practice is “not of Jesus”. Megan Lawton meets teachers of Christian yoga and those who don't believe yoga and Christianity can ever be compatible.
