It is not always easy to concentrate your mind in prayer and unite with God. So do not become discouraged and impatient. Instead, try to use the following method: imagine, far away in space, a living, vibrating centre emitting rays of light radiating in all directions to nourish the celestial entities and the many creatures in the universe. This image will direct your thoughts towards the place where the divine presence manifests itself most intensely and you will feel that your prayer is echoed.
The initiates and great masters are in constant contact with this centre of light and their thoughts generate power currents in the invisible with which we can associate ourselves so that we may feel in communion with the Lord.
