I am no authority on "meditation." Indeed, my acquaintance with it could aptly be described as marginal and experiential. Nonetheless, the holes in your position are evident.

The premise of meditation is that there is exists a dimension of awareness that is "meta-rational." Christianity, for example, actually posits the same thing; they call it the spiritual realm, the theater in which the Holy Spirit is active -- you know, the force that convicts men of sin, righteousness and judgment (John 16:8), and implicated in 1 Cor. 2:14-16.

I will tell you what really disturbs many Christians about meditation; and, if you're a Christian, I can pretty well guarantee you won't like it.

Meditation is predicated on the notion that you are not in control. You see, many Christians, no matter what they say, think that they are responsible for their own salvation. Their doctrine says that they can't earn it; but they are also taught that they can lose it by non-conformity. Most people don't seem to grasp that there's no difference: if you can lose salvation by non-conformity, than you are essentially preserving your salvation by conformity.

This is law, not grace.

Meditation is based on an assumption -- in Christian terms -- that there exists a benevolent force in the universe (call it "God") that seeks communion with man. I don't imagine Hindus or Buddhists would put it this way, but Christians will understand this. Jesus said, If you ask your father for bread, will he give you a stone? (Lk. 11 :9-13).

Really, this sort of objection by "Christians" to meditation smacks more of materialism than spirituality. I wonder how many people actually worship the Bible (that is, their own understanding) rather than God or Jesus.
