Keep Hold.
\"Only deep can be answered by deep\"
 to metaphor this might belong.
Extra thought may stir more imagery.
\"Nothing that floats in shallow waters
can to a depth call respond\"
*
A poetic translation goes as follows.
*
Needed is bottomless care of those 
despondently sinking. 
   
Helping tough passage thru\' flood     
succeeds better if all 
having struggled before keep hold 
of thrown life-rafts given
in love so others can climb aboard.

Hope this ode gives food for thought.
