At the age of thirteen, I was a project of a cursed poet and misguided philosopher. In a tattered notebook I recorded a terrible discovery: the only two sure things in life are death and suffering. Unfortunately, 'adolescence' - which is a suffering for everything - did not let me go beyond the dark pessimism of that realization. That precocious-minded child grew up cursing and disowning pain. It took me half a century of life and much assistance from my Angels, Guides and Masters to understand the function of pain. Pain is not sought, it is not wanted, but it can be used. I learned that there is almost nothing more important than finding meaning in suffering. In it are hidden key pieces to understanding the meaning of existence. It is not about being sinister or masochistic. But it is a fact that happiness does not explain life. Any fool can be happy, but not everyone knows how to overcome pain. When you can't get rid of something, you need to recognize it and understand how it works. If you understand the pain, even if only in part, everything changes. It changes your perspective and, with it, your perception of life. Everything I know about pain from the human and the mystical is in this book, analyzed in the most rigorous and accessible way God has left me. May it serve you well, Wayfarer.
