Below is a link to an excellent article on yoga by Rev. Dr. Ed Hird who is the former National Chair of Anglican Renewal Ministries Canada and Past President of Alpha Canada. Rev. Hird has his own history in eastern religions through exposure in the martial arts and he discusses his journey in coming to renounce his involvement in these activities. This article is very well researched and very thoughtful in detailing the spiritual issues that Christians should understand about the background and spiritual dynamics of yoga. Promoters of “Christian(ized) yoga” should give Dr. Hird the benefit of the doubt as they read this article.
