An explanation of the verse (Tehillim 139:5): “behind and before you have restricted me, you placed your hand on me”.
And he interpreted: because “the living-beings were running and returning” (Y’khezkeil 1:14), and the life-force of the human is in the secret of expansion and constriction, and when a person’s daas is given to know that ze is in constriction, by means of this daas the dinim are sweetened in their source, because the five gevuros mantzepach are in the daas of zeir anpin.
