I don't know what version of the Bible you're using, but you need to toss it and find a better translation.
Luke 11:27-28 As he said these things, a woman in the crowd raised her voice and said to him, Blessed is the womb that bore you, and the breasts at which you nursed! But he said, Blessed rather are those who hear the word of God and keep it!
Jesus did not say *Blessed is Mary.* That is a total corruption of the account and you need to ditch it as such so you don't fall into greater deception.
Mary kept Him in her womb and followed Him to the Cross. That IS hearing and keeping, both in physical and spiritual sense; hence the correction in Christ’s words.
speak about falling into deception......
