Every human being search for something, but does not know precisely how  to define it.

Something that makes him feel his Interior Peace.
In the internal reality of each one, we want to answer simple
questions such as: 

Who Are We?   Where Do We Come From?
Where Are We Going To?   What Are We Doing Here?

The true understanding do not necessarily flow of a lot of accumulated and orderly knowledge or according to logical patterns, some knowledge, perhaps the essential has to come out of the intuition.
