The prayer she asks for everywhere she appears.
The Rosary is the most powerful prayer in the world outside of the Mass itself.
It is not a formula. It is not a ritual. It is a conversation with a Mother, held in your hands, bead by bead, mystery by mystery. It is the story of her Son's life, death, and resurrection prayed through her heart. When you pray the Rosary, you are walking through the Gospel with the woman who lived it.
Our Lady has asked for the Rosary at virtually every apparition in history. At Fatima, she said, "Pray the Rosary every day." At Medjugorje, she said, "Let the Rosary always be in your hands as a sign to Satan that you belong to me." At Gietrzwałd, her very last words were, "Pray the Rosary zealously!" At Cuapa, she showed Bernardo a vision of how the Rosary began, a procession of saints in white, meditating on Scripture as they prayed each decade.
She does not ask for the Rosary because it is easy. She asks for it because it works. She told the visionaries at Medjugorje, "Through fasting and prayer, one can stop wars, one can suspend the laws of nature." She told Sister Agnes at Akita, "The only arms which will remain for you will be the Rosary and the Sign left by my Son." At San Nicolás she said plainly, "The weapon that has the greatest influence on evil is to say the Rosary."
If she asks for it everywhere she goes, we should be praying it everywhere we are.

Traditional Rosary
The Rosary most Catholics know and love. Twenty decades meditating on the Joyful, Luminous, Sorrowful, and Glorious Mysteries of the life of Christ and his Mother. This is the prayer that has sustained the Church through persecution, war, and every trial the world has thrown at it. It is the prayer she places in our hands at every apparition and the one she asks us to pray every day.

Rosary of the Seven Sorrows
It meditates on the seven moments of deepest anguish in her life, from Simeon's prophecy to the burial of her Son. She asked that it be prayed every Tuesday and Friday, and she said it was one of the most powerful tools in the world to defend against temptation and evil. She gave this prayer to three girls in Africa twelve years before a genocide, because she knew that only by entering into her sorrow could they understand the cost of turning away from God.

Rosary of the Mystic Rose
At Montichiari, Italy, Our Lady appeared with three roses on her chest: white for prayer, red for sacrifice, and golden for penance. The devotion associated with Rosa Mystica centers on the Hour of Grace, December 8 at noon, and on the three roses that heal the three swords piercing her heart. This Rosary is prayed especially for priests and consecrated souls, because it was for them that she came, and it was their failures that pierced her most deeply.
