The Holy Rosary, has always been a powerful weapon against heresies, troubles and the demon (satan). Satan hates so much the Holy Rosary that he will try by any means so that no one will pray it.
While nonCatholics see the Holy Rosary as a mindless chant, what they don't understand is that the Rosary is a meditation on the lives of Mary and Jesus. For each recitation of Hail Mary we ask to our Mother for her intersection before God, for our daily life and our dificulties but especially we ask her help for the hour of our death. We Catholics see in Mary a Mighty Virgin who acts with Jesus for the salvation of souls. NonCatholics only see in Mary to the mother of Jesus who brought him into the world and nothing more.

Each decade (each set of 10 Ave beads in the circular part of the Rosary beads) represents a single Mystery in their lives, and as the prayers are prayed, we contemplate that particular Mystery.
