YAUH is a novel full of symbolic messages for humanity, hidden in vivid metaphors concerning the life of a human being that has to integrate and be a part of other entities, of other elements of nature to discover the meaning of life. YAUH is a man who looks for the secret of life and in his eternal search he transforms and integrates to the nature of diverse elements that he discovers in his trailed. In the trajectory, YAUH finds and discovers the human passions: anger, compassion, impatience, hate, love and, finally, his real identity. In every character and with every experience, YAUH is enriching himself and discovering the Universe. His way takes him finally to the knowledge of life by means of a woman's love, and of his real parents, and this way he comes to the infinite, to the eternal. This intuitive and subtle novel takes the reader by the hand, so that, on having reflected on each of the experiences of YAUH, he or she analyzes his or her own inner life. Ecologically universal, YAUH is an extraordinary novel of love to nature. Beatriz V. * * * Alejandro Cuevas-Sosa was born in Yautepec, Morelos, Mexico, in 1939.
