Stars and People

Several months ago, before I slept at night, suddenly I was remembering the words of mothers who grow rice in the my father’s rice field. "Lintang iku ngambarno wong-wong nang ndonyo, ono seng cilik kelak kelik koyok wong susah, ono seng gede terang koyok wong sugih loman" the mother said.
"Stars in the sky that describes the people on earth, there is a little like someone who is poor, there is a big as a rich and generous man," the mother said.
In awake I think it again, "may be true, the star describes the people on earth ".
There are little white dwarfs (stars that faced destruction, what was it describing?), There is the giant betelguese (star will explode, I think it represents the capitalist system, J), there is the light of Sirius (representing the benefactors people), there is a own (lonely, maybe like me, J), there is a clustered (I think this is a big family), there is a bright (he was excited), there are dim (may be, someone who need a friend), sometimes higher sometimes lower position (this is man's life journey).
Their number more than the men but they all obeyed, not as human beings are most arrogant and greedy.
They sometimes become friends for a lonely man, also a guide for people who lost, like a word in Holy Qur’an, which means "And (He created) the signs (the guide). And from the stars they got a clue (an-Nahl:16)".
