Musar su Salmi 116:9

And how much more does this apply if he toils in Torah for pure motives! For Torah study is the choicest of the commandments. Therefore his reward will be redoubled many times. And when he passes away the Prince of the Divine Countenance, the angel MTTRON, along with all the hosts of Heaven will accompany him and dress him in all sorts of precious garments and crown him with crowns. Then the Prince of the Countenance will kindle before him lamps fashioned from the majesty and splendor of the Shechinah. Concerning this did King David and our teacher Moshe pray when they said, I will walk before Hashem in the lands of the living” (Tehillim 116:9). Therefore let a person pray at all times that the Holy One Blessed is He, in His abundant mercy and lovingkindness, save him from every sort of iniquity, transgression and vain deed. And may He guide him along the straight and goodly path. For the Holy One Blessed is He, the Master of Mercy, hears the voice of one who beseeches Him with a broken heart and He will grant him a heart of flesh imbued with purity. Then will “Hashem’s desire flourish in his hand” (Yeshayahu 53:10), Amein.
