We visualize others as a particular number in the maths of this world. Each of them are a certain number ( a 3 or a 100). But in the total maths of the world we are not able to find the number which represents us. So throughout our life we try to find the number that represents us. Am I a 150 or 6645?
The above paragraph tries to explain the search within each of us. The search to know Who we are?, What is our purpose in Earth?, Where do we fit in the System?, etc. Throughout our life we analyze many people and try to find their nature, attitude, etc. But when we try to analyze ourselves we fall short of words( or numbers). Thus it is easy to know about others but tough to know about ourselves.
