The above equation allows us to form the idea that the Universe is ever expanding. The very Universe which is said to contain all hungers for more.
Nature is never perfect, never successful or satisfied. It draws curves in a million ways but is unable to draw a straight line.
Then how come human who are children of Nature herself be satisfied with the little they have got? If they touch the moon, they crave for sun. If they touch Sun they crave for further stars.
You set a goal and then you may reach it. Then you set another goal and life goes on. Does any person after reaching a goal ever feel that,”My purpose of life is over. Now I can simply rest in peace.”
Any person, whoever on the Earth it is, dies trying to reach a goal. Then why does a man need goal if satisfaction will never come, purpose shall never be fulfilled? So why set a goal? Funny thing is that without goal satisfaction doesn’t come either.
If you can understand this one quote you shall understand the answer. If not, you may as well ask me.
