O THOU undaunted daughter of desires!
By all thy dower of lights and fires;
By all the eagle in thee, all the dove;
By all thy lives and deaths of love;
By thy large draughts of intellectual day,
And by thy thirsts of love more large than they;
By all thy brim-fill'd bowls of fierce desire,
By thy last morning's draught of liquid fire;
By the full kingdom of that final kiss
That seized thy parting soul, and seal'd thee His;
By all the Heav'n thou hast in Him
(Fair sister of the seraphim!);
By all of Him we have in thee;
Leave nothing of myself in me.
Let me so read thy life, that I
Unto all life of mine may die!

Richard Crashaw
