One of the most popular prayers in the Catholic Church is the "Come, Holy Spirit" prayer (Veni, Sancte Spiritus in Latin). It is a prayer that invites the presence of Holy Spirit into your life and asks for spiritual strength.
The prayer is especially effective at stirring within us the fire of God's love and the ability to listen attentively to God's voice in our hearts.
Many saints have recommended praying this prayer daily and letting the Holy Spirit guide all our actions.
