It's common sense knowledge that millions of Catholics pray the Rosary and make devotion to Mary an integral part of their everyday spirituality. See for example this [answer](https://christianity.stackexchange.com/a/86690/50422) to the question https://christianity.stackexchange.com/q/86688/50422

Many books have been written on the reasons for and the benefits of praying the rosary and having a genuine devotion to Mary, such as:

- [True Devotion to Mary: With Preparation for Total Consecration](https://www.amazon.com/True-Devotion-Mary-Preparation-Consecration-ebook/dp/B0083Q18B8)
- [Total Consecration Through the Mysteries of the Rosary](https://www.amazon.com/Total-Consecration-Through-Mysteries-Rosary/dp/1622824504/)
- [The Rosary Prayer by Prayer](https://www.amazon.com/Rosary-Prayer-Mary-K-Doyle/dp/0967744946)
- [The Secret Of The Rosary](https://www.amazon.com/Secret-Rosary-St-Louis-Monfort/dp/0895550563/)
- [The Hinge of the Hail Mary: The Art of Praying the Rosary](https://www.amazon.com/Hinge-Hail-Mary-Praying-Rosary/dp/B08PJ1LGNH/)
- [Beneath Thy Protection: Finding Jesus in the Arms of Mary: Mary's Mysteries of the Rosary](https://www.amazon.com/Beneath-Thy-Protection-Finding-Mysteries/dp/B09HFSN634/)
- Etc.

**Question**: How do Protestants explain / make sense of the fact that so many Catholics report spiritual benefits from praying the Rosary and having a deep devotion to Mary? If God disapproves of Marian devotion, then how come so many Catholics experience these benefits? Doesn't this contradict / disprove the Protestant position regarding Mary?
