Meditation is a powerful tool to help with the process of enlightenment, transformation and healing. It is also the ultimate tool and bridge to God and the Universe.
Many studies have been done about the medical, emotional, psychological benefits of meditation. In addition, many religions have some form of meditation in them including the Catholic religion. Some of the early Catholic Saints were quite adroit at meditation like Teresa of Avila.
Although we can get great health benefits and live a more productive life by doing meditation, the ultimate goal of meditation is for the individual to establish oneness with God and the Universe.
