Musar su Cantico dei cantici 1:4

For this is the true joy, namely, that a person's heart delight that he merits to serve before the blessed Master, of whom there is none like Him, and to toil in His Torah and His mitzvot which are the true perfection and the eternal worth. And Shlomo said in a parable on wisdom: "Draw me, we will run after You. The King has brought me into His chambers; we will be glad and rejoice in You" (Shir HaShirim 1:4). For the further a person merits to enter into the inner chambers of knowledge of His blessed greatness, the more his joy will increase and his heart will sing within him. And scripture states: "Israel will rejoice in its Maker; the children of Zion will exult in their King" (Tehilim 149:2).
