Over a number of years, I’ve practiced various forms of meditation from Centering Prayer, which is a Christ-based form of meditation. Meeting with others from a few beliefs, including Eastern beliefs. We would sit quietly. For 20 minutes, and then, when finished, someone would have a piece of writing that wanted to share, and we’d discuss it for 10 minutes or so. After which we’d say a prayer. I’ve also tried a three-hour Eastern religion meditation.
