The month of May is a perfect time to celebrate the divine Mother, and the Virgin Mary is such a universally adored manifestation of the female aspect of God. Here's a prayer that is often said to mother Mary:

Memorare

Remember, O most gracious Virgin Mary, that never was it known that anyone who fled to your protection, implored your help or sought your intercession was left unaided. Inspired with this confidence, I fly to you, O virgin of virgins, my Mother. To you I come, before you I stand, sinful and sorrowful. O Mother of the Word Incarnate, despise not my petitions, but in your mercy, hear and answer me. Amen.
