Knowledge has no limit. It is like the size of the universe. Endless and infinite.
When I was studying in high school, being from a lower middle class family, I had no money in my pocket and I had no way to entertain in the canteen or market or local fair. I tried some part time work but it was very strenuous and gave little money not worth of it.
So, I had no option except to read books for free in the Govt library where even poor students were welcomed. It went on for a long time and unknowingly and unintentionally I had read so may story books and books and periodicals in hindi as well as in english that I forget to keep a count of them. It was only after 6 years when I completed my graduation and left the town for doing post graduation on a very good scholarship that I found that I have almost read the whole library barring a few english literature books and poetry books.
The result was fantastic. I was ready to participate in any discussion. I could prove very easily that God is there or God is not there. Give me a topic and I will tell you something interesting. I was ready to discuss anything from history to astronomy. How did it happen? I was amazed with myself.
After doing my post graduation, I found that the job condition was very tight and I was wandering here and there. My interview was always good. It had to be. The library was sitting there in the upper storey of my mind. But I did not get a job.
It was very sad and hurting and I thought to change my line and try other jobs which were not in my core area. I tried to apply but failed miserably in the interview. Those subjects were alien to me. I soon came to know that what I learned in my life from that library was a drop from the ocean of the knowledge.
There are so many drops in the ocean of knowledge, in fact more than billions, but we have taken a few of them and rest is there only.
Knowledge is power.
