Fernando and Rafael have been very close friends since they were 10 years old, and since then they have been plotting and collaborating on many projects, many of them without much future, and others with some transcendence, such as ""La Bisagra"" and ""Antoja"" (multidisciplinary websites). But the greatest of all projects has been to participate in Siloism, which was the answer to a long-sought search they shared early on in their lives. This book is their most recent collaboration, Fernando as a poet, Rafael as a draftsman, with a production that has been giving informally for the last 21 years or so. Each one in his field, and in this book they have gathered their ""notes"" on different topics in relation to the internal experience and in two separate media. Much of this production revolves around the proposals of the ""Silo?s Message"" on the internal unity, the sacred, the profound, etc., treated from a graphic and poetic perspective.
