The changing of work into play is effected as a consequence of the presence of a "zone of perpetual silence," where one draws from a sort of secret and intimate respiration, whose sweetness and freshness accomplishes the anointing of work and transforms it into play. For the "zone of silence" not only dignifies the soul at rest; there is contact with the heavenly or spiritual world, which works together with the soul. Those who find silence in the solitude of meditation without effort are never alone.
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.
~ from DARK NIGHT OF THE SOUL by Mirabai Starr, translated by Fr. Iain Matthew
