A state of crisis raises the storm of fear, agitation and anxiety in us and fills the mind with clouds of doubt. Therefore we become momentarily blind to the presence of the Sun.
Or else it throws us into a state of depression and despair that puts a curtain or veil of Night between us and the sun. It also throws us onto the surface consciousness where it is much more difficult to feel the Grace and the Presence. By becoming restless we further obstruct the action of Grace which works best when there is trust and quietude in our being.
All this acts as a vicious cycle wherein our very effort makes us sink deeper into the mud. What is needed instead is to stay as quiet as one can and call upon the Grace knowing well that all else can fail but the Grace never fails us.
