Musar zu Dewarim 8:18

The objective of these commandments is to refine body and soul, and the purpose of that refinement is to establish, or better re-establish a close relationship with one's roots, ראשית. Since we have traversed many stages, ספירות, from the original roots, ראשית, this is a difficult task. Nonetheless as the Torah testifies in Deut. 4,4, it can be done, and it confers a superior quality of life on one. דבקות can be defined as the return of the branch to the stem, to the root. However far removed one has been from the source, the Torah exhorts us never to forget our roots, i.e.: וזכרת כי ה' אלוקיך הוא הנותן לך כח לעשות חיל. "You shall remember that it is the Lord your G–d who gives you strength to do valiantly." (Deut. 8,18). The fact that the מצוה of ציצית also features the exhortation וזכרתם, "you shall remember," demonstrates that a similar purpose underlies that commandment. When we follow accepted methods of exegesis, we have both the similar sounding words, i.e. גזרה שוה, present in those two מצות, as well as the references to לדורותיכם, "throughout your generations," which, when applied to former generations, is similar in meaning to ראשית, beginning, or root. The thrust of all this is to remind us that ultimately all our capabilities are rooted in G–d.

And a man who has a job or some occupation by which he supports his family should not think, "If not for this job I would be utterly lost." But he should trust in the Creator may He be Blessed, and think that if this work were not here to occupy him, then the Creator may He be Blessed, would provide his sustenance through some other means, because all the work of his hands and his needs are in the hands of God, and God has many messengers (of good fortune), as Scripture says : "For there is no restraint of the Lord to save by many or by few" (Samuel 14:6), and it says further : "It is He who gives power to get wealth" (Deut. 8:18), and it says : "Not by might nor by power but by My spirit says the Lord of Hosts" (Zech. 4:6).
