The following prayer is the prayer every Missionary of Charity says before leaving for his or her Apostolate. It is also used as the Physician's Prayer in Shishu Bhavan, the children's home in Calcutta:


Dear Lord, the Great Healer, I kneel before You,
since every perfect gift must come from You.


I pray, give skill to my hands, clear vision to my mind,
kindness and meekness to my heart.


Give me singleness of purpose,
strength to lift up a part of the burden of my suffering
fellow men, and a true realization of the privilege that is mine.


Take from my heart all guile and worldliness,
that with the simple faith of a child,


I may rely on You.

perhaps this can be our prayer too...
