"Meditation" has about as many definitions as "Christian". So let me explain what I mean. First, your mind has to agree to shut-up. Second, your senses have to be paying attention. Third, the operating orders from God are "Be still and know that I am God." Finally, breathing is important; as it always is. That's it. No mantras, no special positions. Just be there with God in his time.
Mostly it "works", and mostly it is a blessing.
