For Illumination

SHINE into our hearts, O loving Master, by the pure light of the knowledge of Yourself. Open the eyes of our mind to the contemplation of Your teaching, and put into us the fear of Your blessed commandments; that trampling down all that is worldly, we may follow a spiritual life, thinking and doing all things according to Your good pleasure. For You, are our sanctification, and our illumination, and to You we render glory, Father, Son, and Holy Spirit, now and ever, and unto ages of ages. Amen. (Eastern Church Liturgy; Day-break Office.)
