Some excerpt from a book I enjoyed reading,

"The other morning i heard a 4 year old girl ask her mother, "why was i born into this world? to go to nursery shcool?" Naturally her mother could not honestly say, "yes, thats right, so off you go". And yet you could say that people these days are born to go to nursery school. Right up through college people study diligently to learn why they were born. Scholars and philosphers, even if they ruin their lives in the attempt, say they will be satisfied to understand this one thing. Originally human beings had no purpose. Now, dreaming up some purpose or other, they struggle away trying to find the meaning of life. It is a one-man wrestling match. There is no purpose one has to think about, or go out in search of. You would do well to ask children whether or not a life wihtout purpose is meaningless. From the time they enter nursery school, people's sorrow begin. The human being was a happy creature, but he created a hard world and now struggles trying to break out of it.
In nature there is life and death, and nature is joyful.
In human society there is life and death and people live in sorrow."
