חסידות אויף בראשית 32:32

And this that is said regarding our father Yaakov, PBUH, "and the sun shone as he passed Penuel [and he as limping at the thigh]" (Genesis 32:32) meaning the "Sun" is lucidity and great holiness, that was shining and illuminating him as he passed through Penuel. Penuel is an expression for Panu El, [vacating God] and this is when a person separates their awareness from holiness, then, immediately, "and he limps on his thigh", meaning, that one has a lack in the thigh. And when he [Yaakov] passed through Penuel, meaning, that he did not separate his awareness at all from holiness, and this why then "the sun shone to him".
