Effects of Chanting rosary in a person’s life:

1, It is called “Angelic Psalter” (also known as "Our Lady's Psalter" or "Mary's Psalter"), a powerful tool to Awaken the Soul. An awakened soul is at the presence of god. God's will only reflects on an awakened soul. The name "Psalter" refers to the Book of Psalms, which contains 150 psalms. In the early Church, monks recited all 150 psalms weekly. For the laity—many of whom were illiterate—the "Angelic Psalter" was developed as a substitute, replacing the 150 biblical psalms with 150 "Angelic Salutations" (Hail Marys).

2,Rosary is a meditation tool  to calm the heart and mind, find peace, and grow in meekness by focusing on the life of Jesus and Mary through rhythmic prayers and contemplating mysteries. Its repetitive structure helps ease anxiety and emotional stress, fostering inner calm and spiritual strength.

 3,Rosary helps brain to  focus internal state. 

The Rosary helps focus the brain on an internal state by using repetitive vocal prayers and bead-counting as anchors for mindful meditation, quieting mental chatter (monkey mind- (restless, distracting thoughts)), promoting cognitive control, fostering a sense of peace, and drawing attention to spiritual "mysteries" (scenes from Jesus' life), creating a structured path for contemplation and reducing stress

4. Rosary helps Focus Intellect - help to balance Imagination and thinking.

The Rosary serves as a powerful tool to focus intellect and balance imagination with thinking by blending vocal prayer with meditative contemplation of "mysteries," using the beads as tactile anchors to guide the mind, reduce mental clutter (cognitive overload), and foster a state of calm, deliberate focus, akin to mindfulness, but with a specific spiritual purpose. It trains concentration by repeatedly redirecting wandering thoughts back to the meditations, helping to manage distraction and promote inner peace

 5,Demonic forces do hate and flee from the Rosary praying places and people. Rosary is a powerful spiritual tool, a "weapon against evil" that protects against spiritual oppression, including demonic influences and "demonic depression”. The daily rosary drives them out and keeps them out.

During an exorcism, Satan said to Father Gabriele Amorth, Vatican Exorcist through the possessed person: 'Each Ave Maria of the Rosary is a blow to my face. If Christians knew the power of the Rosary, it would be the end of me. '.

6,Holy Rosary is most effective Contemplative tool to comprehend and experience the works of sanctifying grace to union with Christ.

Rosary meditate on the life, death, and resurrection of Jesus through Mary's eyes, fostering deeper faith, union with Christ, and experiencing God's grace through its scriptural prayers and rhythmic repetition, moving from rote recitation to heartfelt contemplation. It's a journey through the Gospel that unites the faithful with Christ's saving work, offering peace and spiritual growth.

7,Fervent rosary can powerfully enforce sacramental life.

Fervent rosary strengthens faith, draws one closer to Jesus in the Eucharist and Reconciliation, helps overcome sin, and leads to greater reliance on the Church's sacraments for grace. It's seen as a "weapon" for spiritual warfare, fostering holiness, virtue, and a deeper connection with God through Mary's intercession, ultimately leading to a richer sacramental participation
