Dark and Light

This dark is so deep
And the light is so bright
I am blinded by the darkness
I am blinded by the light

Though desire to expound this thought whelms over me, have I yet come up deficient? How to explain that antitheses have the same outcome? What is learned by this observation, if anything? Is there also a realm antithetical to the result of the aforementioned antitheses? Cannot both illumine as well? Are there not things that can only be seen in the dark and not in the light? Is not the dark of life as illuminating as the light of life? Do not we purport that the shadow proves the sunshine? Is it not also true that the light proves the dark? Then, again, what to make of this? Do not blinding and illuminating also have similar effects? Do not they both cause one to ‘see’ in a different manner than formerly? What to make of existence in the dark? What to make of existence in the light? If both yield the same harvest, then ought not both be held equally? Where is God in the spring and summer of life? Is God not there? Where is God in the winter of life? Is God not there too? Does not God pervade all? Is God in the light? Is God not also, then, in the dark?
