For the Sufis, there is no greater punishment than to feel nostalgic for being separated from the source, nor greater reward than to feel attached to it. Thus, the emotion that predominates in this work is nostalgia, and its consequent yearning to break free from it and merge into Unity.This is the story of a fall, a loss, a recovery and an ascension. It is the story of a search for light from the deepest darkness. It is written in poetic prose, with brief fragments independent of each other, which can be read in isolation, but that have a certain cohesion, since each fragment carries, or craves, a little more light than the previous one.It is about a man who has lost his light, but who harbors a faint flash of memory of her. That transience tortures his mind and makes him embark on a path of ascension to recover that precious treasure. It goes through all phases of depression, sadness and melancholy, rejoicing in its loss. In the initial phases he identifies that lost light with the love of a woman, with the love of many women who are one for him; and the loss of that love is the germ of his melancholy. As he progresses in his tribulation, he recognizes that this yearned light belongs to something more subtle and deep, to the realm of his soul… He recognizes that emotional pain comes from feeling separated from the primordial source.This work is written in a somber language, but in its background aims to convey beauty, hope and joy.
