Yes, asking the "universe" for stuff is not Christian. We don't worship the "universe", we worship God.
Meditation and mysticism can be Christian. People like St Ignatius of Loyola and St John of the Cross were Christian mystics and are responsible for a lot of Christian meditation, and the Rosary is a form of meditation. Things like yoga, reiki, New Age stuff, astrology, etc aren't Christian because they're either inherently pagan concepts (like yoga) or encourage you to trust in created forces instead of God (like astrology and fortune telling).
