Oblivion

Turning and turning in the widening gyre
The falcon cannot hear the falconer;
Things fall apart;
the centre cannot hold.
 - William Butler Yeats

Or as Geoffrey Shugen Arnold of the Mountains and Rivers Order of Zen Buddhism explains it, our sense of difference pervades human consciousness. Because of this, we draw lines where none exist and give rise to hatred and violence. If we want to create real peace, we must understand how such anger and hatred arise.
