We don't need to be literate, or to read any book to hear "god's voice". It is in us, in every human being, no matter what race, nationality or religion he/she is. Our conscience is only way to our soul, or way to understand higher meaning and wisdom of our self and existence.

Books are precious because they represent specific development of other people conscious, what can stimulate and enrich our own conscious, and on that way enable us for higher quality of our inside interaction.

But, books can't help us find meaning if we don't do inside interaction or do what is necessary in our self. It is always up to us what we will choose, or how we will choose to develop our conscious: in meaning or understanding of essence, or trough low consciousness of appearance and illusion.
