We realize--often quite suddenly--that our sense of self, which has been formed and constructed out of our ideas, beliefs and images, is not really who we are. It doesn't define us, it has no center.
This moment in which you experience stillness is every moment. Don't let the mind seduce you into the past or future. Stay in the moment, and dare to consider that you can be free now.
The unknown, our own true nature, has the capacity to wake itself up when you start to fall in love with letting go of all the mental structures you hold onto. Contemplate this: there is no such thing as a true belief.
When you rest in quietness and your image of yourself fades, and your image of the world fades, and your ideas of others fade, what's left? A brightness, a radiant emptiness that is simply what you are.
