This volume is dedicated to secularity defined as "sacred", that represents the lifestyle to which we are called, overcoming the dichotomy between the sacred and the profane. It is not a question of escaping the world, but of transfiguring it - which is more than redeeming it: it is resurrecting it. We must "find" the sacred and "create" the secular way. The discovery of sacred secularity is the catalyst to ensure that the transformation is not just a change of dress, a new fashion, but a historical mutation. The task is not easy, but it is urgent and also fascinating. This volume invite us to understand the transformation: the fall of the buzz into silence. It tries to present a vision of the world in which, without denying the possible transcendence of the divine, the immanence of the sacred is accentuated in the very depths of the world. For too long, the so-called religion has tried to reunite us with a transcendent Being at the expense of the immanence of Being in beings, thus causing the splitting of man's being with the Being of all reality.
