Devotion
Marian
What it is
Marian names what belongs to the Blessed Virgin in the Church's life: her liturgical feasts, the Marian antiphons of Compline, hymns such as the Salve Regina and Flos Carmeli, the rosary, scapulars, and the doctrine that she is Mother of God and Mother of the Church. The honor given her is hyperdulia—veneration above the saints, never the worship due to God alone.
What it is not
Marian devotion is not goddess-worship. It is not optional sentiment for "Marian types." It is not a rival to Christ—every true honor of Mary terminates in Him. It is not exhausted by aesthetics (blue, roses, soft music) without doctrine and imitation of her fiat.
How a Catholic encounters it
Keep her feasts. Pray a Marian antiphon at night. Learn one Marian hymn in Latin. Wear a blessed scapular if you take the devotion seriously. Ask her intercession as a son asks a mother—then do what she says: Do whatever He tells you.
