Mary is God's great gift to us. From the cross, Jesus gave her to us as our Mother. This makes us brothers and sisters to Christ. Since the Lord gave her to us, then of course, we can communicate with her. That's why we talk to her, asking her in intercede for us before the Father.
I love Holy Mother for the following reasons: (1) She suffered greatly for the Lord's Passion. (2) She's a most special and dear gift given to us by God. (3) She always brings us closer to Jesus. (4) She's most holy, most beautiful, and most loving, a perfect model for us to imitate.
