Holy Mother, one and only Mother, Mother immaculate, Mother of clemency and of mercy, open thy compassionate heart, and receive one, whom his sins had rendered dead. 

-St. Anselm, de Concept.

My lips, O my Queen, are not able to utter the words, for my heart is incapable of conceiving them: my inmost being is troubled with the desire to render thanks to thee for all thy favours; but thoughts that are worthy of thee come not into my mind, and I shrink from offering such as fall short of what is thy due.

-St. Anselm, Orat. ii.
