Duality: between darkness and light

We have been taught to be afraid of darkness, we are always shown darkness as the place of perdition where souls suffer, this belief is so ingrained in humanity that we constantly find ourselves fighting with our own darkness, we fight to expel it from the depths of our soul to find peace. However, in some moments of meditation I have thought: How bad is darkness? Is our longed-for peace really found in the absence of darkness in our soul? Yes I know these are strange questions but my restless mind has often asked them. In my opinion, light and darkness create a balance, a perfect equilibrium... one does not exist without the other, neither is good nor bad. And most probably it is not so, but I believe that to transcend it is necessary to accept our light and our darkness as part of a whole, a duality.
