Prayer to Know One's Vocation

Behold me at your feet, O Virgin most kind,
seeking to obtain through you, the most important grace of knowing what I ought to do.  I desire nothing but to comply perfectly with the Will of your Divine Son at every moment of my life. Mother of Good Counsel, let me hear your voice.  It will dispel every doubt that troubles my mind. 

I trust in you, being confident that since you are the Mother of my Redeemer, you will also be the mother of my salvation. 
If you, O Mary, will not send me a ray of the Divine Son, what light will enlighten me?  Who will direct me if you refuse, who are
the Mother of the Uncreated Wisdom? 

Listen then to my humble prayers.  Let me not be lost in my uncertainty and instability.  Lead me along the straight road that ends in life everlasting, you who are my only hope, and whose hands are full of the riches of virtue and of life, and who dispense the fruits of honor and holiness.  Amen.
