The Tao Te Ching says that the source of everything is called "darkness," What a beautiful name (if we must have a name)! Darkness is our source. In the end, it embraces everything. Its nature is love, and in our confusion we name it terror and ugliness, the unacceptable, the unbearable. All our stress results from what we imagine is in that darkness. We imagine darkness as separate from ourselves, and we project something terrible onto it. But in reality, the darkness is always benevolent. . . .
The reason that the darkness is the gateway to all understanding is that once the darkness is understood, you're clear that nothing is separate from you. No name, no thought can possible be true in an ultimate sense. It's all provisional; it's all changing. The dark, the nameless, the unthinkable — that is what you can absolutely trust. It doesn't change, and it's benevolent. When you realize this, you just have to laugh. There's nothing serious about life or death.— Byron Katie in A Thousand Names for Joy
