Be content with what you have;
rejoice in the way things are.
When you realize there is nothing lacking,
the whole world belongs to you.

~Lao Tzu

“The emergence and blossoming of understanding, love, and intelligence has nothing to do with any tradition, no matter how ancient or impressive—it has nothing to do with time. It happens on its own when a human being questions, wonders, inquires, listens, and looks silently without getting stuck in fear, pleasure, and pain. When self-concern is quiet, in abeyance, heaven and earth are open. The mystery, the essence of all life, is not separate from the silent openness of simple listening.”
Toni Packer
