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 their own field, and in this book they have gathered their ""notes"" on different topics in relation to the internal experience and in two separate media. Both artists draw their inspiration from the experience contained in "Silo's message," a spiritual path based in the search for meaning in life, overcoming suffering and finding transcendence in the depths of the mind. This book is an account of that experience.
