If you read the bible, you would realize that the Blessed Virgin Mary says only one thing: Do what he (Jesus) tells you.”
There is much meaning in that simple phrase. Much symbolism.
As a former Catholic, I seem to remember in the '60's (I think), a "message from Mary" that had been on hold for a number of years that asked we pray the rosary daily.
I forget the exact details.
The Rosary is essentially 90% Mary and 10% God, with the exception that Jesus is Mary's child (" .. blessed is the fruit of thy womb, Jesus" ), He isn't too much a part of the Rosary.
