E.W. Jackson, the really, really socially conservative Republican Lieutenant Governor candidate in Virginia, has written a book decrying Yoga as one of those things, along with the homosexuals, that are destroying America:
When one hears the word meditation, it conjures an image of Maharishi Yoga talking about finding a mantra and striving for nirvana. . . . The purpose of such meditation is to empty oneself. . . . [Satan] is happy to invade the empty vacuum of your soul and possess it. That is why people serve Satan without ever knowing it or deciding to, but no one can be a child of God without making a decision to surrender to him. Beware of systems of spirituality which tell you to empty yourself. You will end up filled with something you probably do not want.
This is via National Review reporter Betsy Woodruff, who, to her credit, puts the book excerpt in a blog post, but bafflingly left it out of her Jackson profile because it "didn't make the cut." Yeah, no room for a detail like that in a magazine profile.
