Shabbos and Divine Work

The Chidushei Harim ZY”A said that Shabbos must be שיהי' כל מלאכתך עשויה - all your work should be as if accomplished. Not only in Gashmius - mundane issues. Also, in Ruchniyus – spiritual ימנ םימש תכאלמ in divine work. To understand that the קורת רוח - pleasure of Shabbos should make forget all unhappiness.
