Here is a beautiful prayer by Blessed Cardinal John Henry Newman.
This Prayer was recited daily after Communion by Saint Teresa of Calcutta and her Sisters of Charity.
Help me to spread Your fragrance wherever I go.
Flood my soul with Your spirit and life.
Penetrate and possess my whole being so utterly,
that my life may only be a radiance of Yours.
Shine through me,
and be so in me that every soul I come in contact with
may feel Your presence in my soul.
Let them look up and see no longer me, but only Jesus!
Stay with me and then I shall begin to shine as You
so to shine as to be a light to others.
The light, O Jesus, will be all from You;
none of it will be mine.
It will be you, shining on others through me.
Let me thus praise You the way You love best,
by shining on those around me.
Let me preach You without preaching,
not by words but by my example,
by the catching force
of the sympathetic influence of what I do,
the evident fullness of the love my heart bears to You.
