I pray to God. The image is of light, energy, and all the things that I cannot comprehend. It is "the creator", "the source", or God; pick your preferred definition. It is what is there that words cannot begin to describe and thoughts cannot begin to comprehend. Infinite, timeless and what the ancients referred to as Yahweh - a name that they were reluctant to speak simply out of reverence. Depending on the circumstances, sometimes there are images of Jesus are there as well, most times not.
