Seeking

I've struggled with this too, but have since largely got over it.  I choose to the see existence through the lens of light and dark.  Neither is "bad" or "good" per se, they just are, and they do different things.

An aspect of the darkness is conformity, and this goes back to nature of visible darkness.  When you have total darkness, you see nothing but black.  Pitch black = total conformity.  Add just a touch of light and now you've got a little bit of gray, which is no longer total conformity.  Darkness tends in the direction of total conformity while light tends in the direction of total diversity.  The reason I say that neither light or dark are "good" or "bad" is that total diversity isn't necessarily a "good" thing either as it could easily become total chaos.  I digress.

When you think you have a monopoly on truth and thus want other to see things as you do, what are you doing?  Pushing for more conformity, which is an aspect of darkness.  What the light does is just what physical light does: it shines onto things that someone might not have seen before so they can observe it for what it is and then choose to see it for how they want to see it.  It shows the color, the shape, the texture and other things.. but it doesn't label, define or decree things as "good" or "bad."
