Nothingness is the space conducive to powers, beginnings, the birth of new ideas, creativity, mental dexterity, understanding and speech; It is analogously present in zero, in emptiness, in change, in movement, in substantial modifications, in silence, in losses and in meaninglessness. It is there, in the nothingness that contemporary man still has, where he must reconstruct himself to achieve his fullness. The consideration of nothingness implies a new perspective, an alternative perspective, a vision different from the conventional one. That, being a swimmer, is what this work suggests. In its pages, the reader will find a model to understand existence and what happens in it, a support from which to intimately assume that denying oneself is the only way to affirm oneself, that leaving is a way of being, that destroying oneself is a way of building and that not being is also a modality of being. For all this, the contemplation of nothingness, the central proposal of this book, allows us to admit that silence speaks more than the voice, that emptiness is a form of presence, that zero counts more than unity and that nothingness, turned Nothing, entirely surpasses our being.
