"The simple fact is that we live in a world of conflict and opposites because we live in a world of boundaries. Since every boundary line is also a battle line, here is the human predicament: the firmer one’s boundaries, the more entrenched are one’s battles. The more I hold onto pleasure, the more I necessarily fear pain. The more I cling to life, the more I am haunted by death. The more I experience war, the more I long for peace. The more I wait, the more time simply flies on. The more I cling, the more I lose."
