Amazing study and an adventure by the author. With his age and foolishness, i felt connected with Carlos, while also noticing how different of a world i see through my eyes. Even though i am a more reason person than spirits, the book has great teachings. The steps of becoming a man-of-knowledge; firstly overcoming fear of unknown to learn properly and being clear, then looking past your clarity to not be blinded by your ego and being powerful. Then, still holding to your character rather than the status your power brings, all until the last enemy, old age takes you down. While we may not be man-of-knowledge, we can still see the lost people of each step around us. Just like this example, i take the teachings as an analogy of the material world and inner thoughts, i recommend the book to anyone that can differ this.
