I like to think that the world is basically black and white and as much as we criticise our inability to destroy evil, and deem that the choice between good and bad has to be made, the choice cannot be made.
I think the reason this world is bipolar, holding onto the existence of two extremes, is because it needs to.
Balance needs to be maintained in the energies. One cannot prevail. Imagine having a completely white worldor black for that matter.
Nothing would make sense.
The dualities exist, perhaps for many reasons, yet to be discovered and comprehended
but I like to think, that it is simply
because as human we need to come to an understanding, that evil and good are two sides of one coin and one without the other,
has no valour whatsoever.
