May the road rise up to meet your feet;
May the wind be always gentle at your back
and the sun shine warm upon your face.
May the welcome rains fall softly upon your fields
And, until we meet again,
may God hold you in the palm of his hand.

 - -  and the similar Friendship Wish:

May there always be work for your hands to do;
May your purse always hold a coin or two;
May the sun always shine on your windowpane;
May a rainbow be certain to follow each rain.
May the hand of a friend always be near you;
And may God fill your heart with gladness and   cheer you.

AN IRISH BLESSING.
