The inner self is as secret as God and, like God, it evades every concept that tries to seize hold of it with full possession. It is a life that cannot be held and studied as object, because it is not "a thing". It is not reached and coaxed forth from hiding by any process under the sun, including meditation. All that we can do with any spiritual discipline is produce within ourselves something of the silence, the humility, the detachment, the purity of heart and the indifference which are required if the inner self is to make some shy, unpredictable manifestation of presence.
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.
