The author wrote this letters or guidances for his son. It was beautifully written, because he wrote it with his heart and with a good purpose.

I found that I can relate with a lot of ideas written in this book, but I also had disagreement with some of the ideas inside of it.

However, just like the author said,
“The truth that you must become accustomed to is that this world of ideas that have no specific religion or ethnicity or even loyalty is not a world to accept or reject. It is like eating. Whatever you consume must be digested. There is no other way. These ideas, once comprehended, must be absorbed and perhaps modified, intellectually or emotionally, to suit your identity and perspective.”
