Saint Ephrem’s prayer to Mary to obtain a pure body and a pure mind

"Most holy Lady, Mother of God, the only one who is very pure in soul and body, the only one who is beyond all purity, chastity and virginity, the only one who dwells in the grace of the Holy Spirit, who surpasses even the spiritual powers in purity and holiness of soul and body, look upon me, guilty, impure, and stained in my soul and body with the defects of my passionate and voluptuous life.

Purify my spirit from its passions; sanctify and straighten my wandering and blind thoughts; regulate and direct my senses; deliver me from the detestable and infamous tyranny of impure inclinations and passions; abolish in me the empire of sin; give wisdom and discernment to my stubborn, wretched mind, for the correction of my faults and falls, so that, delivered from the darkness of sin, I may be found worthy to glorify you, to sing freely to you, the only true mother of the true light- Christ our God."
