It depends on your flavor of Christianity and Meditation. Protestant Fundamentalists would give it a thumbs down if you're practicing Transcendental Meditation complete with the Indian Mantra n' such. They look at it as practicing a heretic religion other than theirs. I have a childhood friend who grew up to be a sleezy TV preacher and he informed me that the Mantra words are actually the names of Tibetian Demons...

I've also heard grave warnings about blanking your mind as this allows demons to enter.
