In most western religious texts, folklore and fairy tales darkness equals evil. Evil that surrounds and infiltrates.
I was a father at a young age (at least I thought it was young). I watched my kids grow up and while growing up I saw them face obstacles, in school, at work, within their friend circles. The obstacles were in form of rocky relationships, steep learning curves, and physical ailments.
The kids and myself were quick within rocky relationships to label people good or evil but that is reductive thinking that I tried to avoid. My dad told me that the most important thing and only thing I could do to make a difference was to do the right thing.
We cannot make someone do good or bad. People have freewill and autonomy. All that we can do is steer our own ships. When we begin to try and influence others through deeds that are not good we risk allowing the darkness to fill us. Darkness is funny that way. We can do bad things in pursuit of good outcomes and then we are the darkness we were attempting to drive out.
In the Christian bible text John 8:12 we are taught that only light or good can drive out darkness. I think a lot about war when I think about light and dark. In war we use harm and force to try and drive out darkness. It seems foolish to assume that war would create good or an end to darkness.
The written book “Soliloquies in England and Later Soliloquies” is thought by scholars to be, part of our civilizations knowledge base. It is a very important book that seems to have guided our society and in it the author says “Only the dead are safe; only the dead have seen the end of war.” — George Santayana

When we work and use darkness we only get pain and death. Darkness is funny that way it does not heal, mend, build, or give any life. Lets make a promise to ourselves today, lets promise that we will not use darkness even if it seems like darkness is the right way. Lets promise to only use light only do good.
