Try visualizations. A St. Ignatius technique.
See the scene in your mind’s eye. If the Lord can use the intellect to help us understand Him, He can use the imagination as well.
Take the 2nd sorrowful mystery as an example. the Scourging at the Pillar. How would you feel as Mary to watch your Son be whipped to such a sad and bloody state while many were jeering at him? Especially so as He is being sacrificed for not only mankind but for the vey people that were whipping Him? How would Mary feel knowning that her Son earnestly desired to suffer this? Would you not then start to learn to appreciate Mary ever so much more? Would you not learn to love our Lord more as well? Would you not begin to understand how much we are loved by the Lord? Would you not begin to understand that if He were to tolerate the scourging for us , would we not begin to understand that there is
no sin he will not forgive if but asked with a contrite heart?

When one ‘sees’ such love it is quite natural to want to love in return. So we grow in love and sin less. This, then learned, love, also assists our fellow man methinks! The prayers of the Rosary -as has been said- is likened unto a dark, stained and dusty Mirror (the soul) placed in front of a warm bright
fire. (God’s Love.) With each Hail Mary some of the grime is wiped off the mirror. Eventually the Mirror reflects the light and the fire of our Lord’s love.
So. Do not just
say the Rosary. (Although know that, at least by just even merely saying the the prayers you are exercisng your will - aided perhaps by the Holy Spirit!) You may just fall asleep!
Rather -be
in the Rosary.
