Open to us Lord, your great door, O Fountain of all mercy, hear our prayer and have mercy on our souls. Lord of the morning and ruler of all seasons, hear our prayer and have mercy on our souls. Shine upon me, Lord, and I shall be light like the day; I will sing your praise in light while I marvel; may the morning awaken me to the praise of your Godhead and I will pursue the study of your word all the day long. With the day may your light shine on our thoughts and may it drive away the shadows of error from our souls. The creation is full of light, give light also to our hearts that they may praise you with the day and the night.
