Please read the second link, translation's a bit rough but you'll get the gist: "HISTORY:
The Most Holy Virgin favored with abundant locutions and extraordinary visions during several years, to Sister Natalia Magdolna (1901-1992), Hungarian nun, born near Pozsony (in present Slovakia), pertaining to the congregation of the Sisters of the Good Shepherd of St. Mary Magdalene of Kecskemet.
Her life was full of supernatural graces and had intense communications with God. She died in an odour of sanctity, at an advanced age.
The promises that we next, are selected from several messages that Jesus and Mary communicated to her, and that were published in the book "La Victoriosa Reina del Mundo" ("the Victorious Queen of the World") by Ediciones Xaverianas, S.A. of C.V. – Ave. Juan Palomar y Arias 694 – Prados Providencia - A.P.1/133-44100 Guadalajara, Jal. (MEXICO).
Fr. Jeno Krasznay, Spiritual Director of Sister Maria Natalia for some time, famous European theologian and Auxiliary of Bishop Isvan Hasz, declared these mystical experiences as legitimate, as well as the visions and messages, after a long period of investigation and examination.
It's an extremely powerful Novena. I encourage all to make it and you will know by experience, as St. Therese once said for a 30 day Holy Cloak Novena to St. Joseph, also very powerful; here, we place devotion to Our Lady's Immaculate Heart next to that of Our Lord's Sacred Heart, just like Jesus asked us at Fatima. We honor the Twin Hearts together and do all our works and actions during the 9 months to make reparation to the Holy Hearts of Jesus and Mary together; I think that's what makes this Novena so powerful.
"I understood that Jesus was requesting the same for his Mother as He had asked St. Margaret Mary for himself. I asked him Jesus:
- Should we also console your Mother, since she receives so much ingratitude?
- Jesus answered:
- Beloved daughter, if somebody hurts me, this person also hurts my Mother. If somebody consoles me, it consoles my Mother, because my Mother and I are one in the love.
When The Savior said this to me, I understood many things on the unity of the Sacred Hearts.
Jesus also said to me that if somebody goes to confession regularly once a month, is not necessary to go to confession before receiving the holy communion, if one has not committed any mortal sin since the last confession. Jesus taught this prayer to me for the first Saturdays:
"Most Sacred Heart of Jesus,
I offer this holy communion
through the Immaculate Heart of Mary,
to console You for all the sins
committed against You".
