Value your parabatai," he said. "For it is a precious bond. All love is precious. It is why we do what we do. Why do we fight demons? Why are they not fit custodians of this world? What makes us better? It is because they do not build, but destroy. They do not love, but hate only. We are human and fallible, we Shadowhunters. But if we did not have the capability to love, we could not guard humans; we must love to guard them. My parabatai, he loved like few ever could love, with all and everything. I see you are like that too; it burns more brightly in you than the fire of Heaven

I always ask myself one question: what is human? What does it mean to be human? Maybe people will consider my new films brutal again. But this violence is just a reflection of what they really are, of what is in each one of us to certain degree.

What humans want most of all, is to be right. Even if we're being right about our own doom. If we believe there are monsters around the next corner ready to tear us apart, we would literally prefer to be right about the monsters, than to be shown to be wrong in the eyes of others and made to look foolish.

The degree of freedom we enjoy outwardly is a reflection of the degree of love we cultivate inwardly.

Force is incomplete and therefore has to be fed energy constantly. Power is total and complete in itself and requires nothing from outside.

After all, it isn't the facts of one's environment, but one's attitude toward them, that determines whether one will be defeated or victorious.
