A reflexion on the eight Beatitudes of the Sermon on the Mount that Jesus of Nazareth left us as Divine knowledge for our benefit. The author believes that these sermons of Christ are addressing even these days the current chaotic situation of our world and our fallen human nature, and affirms that our world disharmony and violence are related to our refusal to accept and manifest in our lives the wisdom of these eight beatitudes, and that if these were truly followed, they could manifest through all of us a new life for this planet and a true path for the construction of a new heaven and a new earth.
