(excerpts from the tract by St. Louis Marie de Monfort)
(no. 7:10) Mary alone has found grace with God, both for herself and for every man in particular. The patriarchs and prophets and all the saints of the Old Law were not able to find that grace. Mary gave being and life to the Author of all grace and that is why she is called the Mother of Grace. God the Father from Whom every perfect gift and all grace come, as from its essential source, has given all graces to Mary by giving her His Son: so that, as St. Bernard says, "With His Son and in Him, God has given His will to Mary." God has entrusted Mary with the keeping, the administration and distribution of all His graces, so that all His graces and gifts pass through her hands; ...
(19:20) There does not exist and never will exist a creature in whom God, either within or without Himself, is so highly exalted as He is in the most Blessed Virgin Mary, not excepting the saints or the cherubim or the highest seraphim in Paradise. Mary is the paradise of God and His unspeakable world, into which the Son of God has come to work His wonders, to watch over it and take His delight in it. ... Happy, a thousand times happy, is the soul here below to which the Holy Ghost reveals the Secret of Mary in order that it may come to know her; to which He opens the "Garden Enclosed" that it may enter into it; to which He gives access to that "Fountain Sealed" that it may draw from it and drink deep draughts of the living waters of grace!
Prayer and frequent Holy Communion must be the answer to entering that "Garden Enclosed". Hopefully, I get to experience the "Secret Garden" before I take my last dying breath.
