The author delves into the mystery of the third person of the Trinity, the Holy Spirit, trying to bring to light more characteristics of His inspiration in our lives, since despite the fact that the Holy Spirit is the great unknown of the Christian tradition, it is, however, the communication that exists between God and his separated children, and the inherent power of the vision of Christ. If we succeed in allowing the Holy Spirit to give meaning to our lives, we can discover that His light is at all times the "follow me" of Jesus.
