Knowledge and Ignorance

As all of us know, knowledge is like an ocean. Why do we need to know? To be aware of the things which we do not know or in case if we know to some extent acquire the full knowledge. Getting knowledge really brings some happiness. One may question that I know everything and I need not get the preaching from you, then we will come to know that he doesn't know himself. This is because there is no person on the earth who knows every thing except the almighty. Suppose a person closes his eyes and says there is no sun, no world and no truth, this is sheer ignorance and not the right knowledge. Just because he has closed his eyes, could there be no sun/moon? could there be no world? could there be no truth? Certainly not and everything do exist and only thing is that the other person has closed his eyes and things are not visible to him which is also termed as ignorance. When once he opens his eyes he comes in touch with all these and says that sun is glowing, World is changing and Truth always wins.  In this context, a person who has the knowledge of a snake only can feel the presence of a snake when he look at rope at a distance.In case if he is not at all aware of the snake or rope , he will not be horrified when he come across a rope as snake. Knowledge makes us feel comfortable, feel confident and we can convince others by means of sharing knowledge with others.
Essence: Knowledge brings happiness and therefore, acquire the knowledge.
              Ignorance keeps us in darkness and therefore come out of darkness.
