This app includes meditations and prayers in order to promote preparation for Total Consecration to Jesus through the hands of the Blessed Virgin, according to the method of St. Louis de Montfort. We develop a roadmap to guide and enrich the month of those who wish to devote fully to Jesus through Mary. The app is divided didactically according to the guidance left by St. Louis himself, in "Treatise on True Devotion to the Blessed Virgin." So do not be afraid to deepen their knowledge of the Virgin, because the more we know and love, the more we will know and we will love to Christ, even being more faithful to His love. This is caused by the fact that total consecration to the Virgin Mary impels us to a renewal of the baptismal promises, helping us to live faithfully our faith in Christ.
