The emptiness of the dark night is a yielding emptiness that gives way to the fullness of all possibility... If all your spiritual activities have grown empty and you are compelled to walk away, tie yourself to one practice only: contemplative silence. Abandon discursive prayer if it has become mechanical and meaningless. Let go of holy images if they no longer evoke the sacred. Refrain from spiritual discourse if it tastes like idle gossip in your mouth. But do not turn away from the silence.
There's a thread you follow. It goes among things that change. But it doesn't change. People wonder about what you are pursuing. You have to explain about the thread. But it is hard for others to see. While you hold it you can't get lost. Tragedies happen; people get hurt or die; and you suffer and get old. Nothing you do can stop time's unfolding. You don't ever let go of the thread.
