Does the sun ask itself, "Am I good? Am I worthwhile? Is there enough of me?" No, it burns and it shines. Does the sun ask itself, "What does the moon think of me? How does Mars feel about me today?" No it burns, it shines. Does the sun ask itself, "Am I as big as other suns in other galaxies?" No, it burns, it shines.
There is darkness inside all of us, though mine is more dangerous than most. Still, we all have it - that part of our soul that is irreparably damaged by the very trials and tribulations of life. We are what we are because of it, or perhaps in spite of it. Some use it as a shield to hide behind, others as an excuse to do unconscionable things. But, truly, the darkness is simply a piece of the whole, neither good nor evil unless you make it so.
