Musar sobre Provérbios 27:10

When the latter describes this verse as speaking about man's soul, what he means is that the words שלמת רעך "the garment of your רע," refer to the elevated soul, נשמה הנאצלת that originates with G–d, which is also known as רע, seeing that it says (Proverbs 27,10) רעך as well as ורע אביך אל תעזוב, "do not abandon the רע of your "father," i.e. see to it that you return it to Him in a state of purity," i.e. when your personal sun sets (when you die). The "widow" then is perceived as having been bereft of her "husband," i.e. G–d, once already, since her soul had to return to earth to inhabit another body. The object of existence is to see to it that you do not need a second round of life on this earth. All this is alluded to when the Torah says that you have to return it to G–d "every night," i.e. after death (night is equated with death).
