During the month of May we honour Our Lady, the Mother of God. We can do this by reciting the Rosary.
The Rosary is the prayer which is most pleasing to Our Lady. The word Rosary meansa garland or wreath of roses and each prayer said in the Rosary is a spiritual rose offered to our blessed Mother.
Our Lady has revealed to several people that each time they say a Hail Mary they are giving her a beautiful rose and that each complete Rosary makes her a crown of roses. The rose is the queen of flowers, and so the Rosary is the rose of all devotions and it is therefore the most important one.
The Holy Rosary is considered a perfect prayer because within it lies the awesome story of our salvation. It's a simple prayer, humble so much like Mary. It's a prayer we can all say together with Her, the Mother of God. With the Hail Mary we invite Her to pray for us.
Our Lady always grants our request. She joins Her prayer to ours. Therefore it becomes ever more useful, because what Mary asks She always receives, Jesus can never say no to whatever His Mother asks for.
In every apparition, the heavenly Mother has invited us to say the Rosary as a powerful weapon against evil, to bring us to true peace.
