Self-forgetfulness tells the troubled and overwhelming story of Charles de Foucauld (1858-1916), a French aristocrat converted to Christianity thanks to the faith and devotion he saw in Islam. Few biographies are as moving and emblematic as that of this strange missionary, who had to go through being an explorer of the Sahara, Trappist novice, messenger of nuns and even author of the first French-Tuareg dictionary -among many other trades-, before discovering friendship as the most beautiful gift of a life given to silence. The reasons for this eventful life journey are found in how much this man heard about himself, as well as in his faithful and implacable obedience to his conscience. Wounded by the passion of the Absolute, who was later known as 'the universal brother' always sought to be less: a more hidden existence, a more anonymous surrender, a deeper humility... Fascinated by this desire for abasement, Pablo d'Ors gets into the head and heart of this extravagant character. The result is one of the most intense and portentous novels of the last decades in the Spanish language. A text in which mystical wisdom resonates and that narrates, with as much plasticity as depth, the dangerous and wonderful extremes to which love leads. An authentic compendium of spirituality for the twenty-first century. A parable of how human failure paradoxically leads to fulfillment.
