Books and an eye

Today when i closed my eyes, i saw books. and an eye. Only one eye. I don`t know what that meant until i thought further...
Why is it that people in history wrote so much? Why would one do that? i mean why is it that i`m writing this blog?
I might say that this gives me pleasure and satisfaction to let people know what my thinking is, what`s my perspective and how different it is from yours or it might say how much intellect i possess and how puny is your thinking (maybe worse) or it is just a piece of fact unrelated to anything about the reader. Something that others might not know but the writer found out spending time and effort. But why would someone give something worth so much (his effort and time) for free or just a couple of bucks.
Lets travel to history to seek the truth, since what we are is the repercussions of what we were.
I am told that in India. centuries ago, the education was for a privileged few. Either those who could afford it like Kings etc. or those whose parents are themselves teachers hence, the Brahmins. But why was it like this, when the cost of information was not too much for a noble man in those times. They worked, came home, ate and took rest, why not is it permitted to them to share the knowledge the same as their highness?
The answer is that the knowledge was a set of secrets that are provided to kings so that they could control these people. Since, brahmins and kshatriyas were the ruling communities that time, they were given education as a source of power to control (manage in other words) the property and people under their custody.
This gave them those select few their share of image boost of being superior in the community since they had the most "secrets". Again, people would praise them a 100 times when they told something from their magical secrets (quote: Budhha) and this gave the story teller another boost in their ego.
But they never knew, that they are themselves slaves to someone else`s thoughts. Those who wrote what they read. That`s the reason they had only one view, only one eye through which they also saw the world. They say it those texts were written/spoken by God himself and those are absolute, above everything that is and ever will be... and i believed that too until this day when i`m writing this post and hoping that someday someone will come and view this blog and praise me for something that he always knew but never stumbled upon. Well, this is life and Praise to my ego is its necessity.
