Musar zu Mischlej 22:21

And whoever God, may He blessed, has graced with intelligence should place into his heart that God, may He be blessed, has sent him into this world to keep His watch, His statutes and His commandments. And he should only open his eyes to do his mission. And at the end of days - if he did his mission trust-worthily - he comes back with joy and with eternal gladness upon his head; like a servant that the king has sent to cross the sea, whose eyes and heart are only upon the matter of his agency until he returns to his master. And likewise did King Solomon, peace be upon him, say (Proverbs 22:19-21), "That you may put your trust in the Lord, etc. To let you know truly reliable words, that you may give a faithful reply to him who sent you."
