" It was interesting, I reasoned, how fire could be so pleasant when it was controlled. It could be used to prepare food or cauterise a wound. It could shed light in the darkness or create warmth. But left uncontrolled, it could destroy villages and forests. It could mutilate and cause hurt.
But that was the same for everything.
Water was a necessity for life, but one could drown in it.
A sword could be used to protect one’s self, but it could contrarily damage the user.
Kind words could put one at the top of the world, while cruel words could hurl another into an abyss of despair.
But the greatest paradox in my life was not the irony of fire, water, weapons, or words. It was the idea that a sanctuary, or asylum, was designed to protect and to be a refuge— to keep away from that which was harmful or hurtful.
But there was a dark catalyst to asylum. One could not keep out the bad without keeping out the good as well. As a wall deterred enemies, at the cost of dissuading friends, so could a sanctuary turn into a prison. "
