It states in this week's parashah (17:15) שום מלך עליך תשים, "You shall set a king over you."
We can explain that "A King" alludes to Hashem. The pasuk is hinting מלך עליך ...שום, make Hashem your King. This alludes to the theme of temimus in thought, action, and speech, which we discussed above. The pasuk is saying (a) Don’t complain about your life because believe that Hashem is your king and leads you in the best way. (b) Do all of Hashem's mitzvos without cutting corners and without compromising. Hashem is king, and we must be devoted to His word. (c) For anything you need, turn to Hashem in prayer because Hashem is your king, and He will listen and grant you your needs.
The Torah writes מלך עליך תשים שום, which literally translates as "You shall set, you shall set, a king over you." It is written double because sometimes you will fall from your level. Once again, you are (a) complaining that your life isn't good. (b) making compromises with your adherence to the mitzvos. (c) avoiding saying sincere tefillos. It is natural that a person will fall from his level, so the Torah writes twice, תשים שום מלך עליך, after you accepted Hashem as king once, do so another time. Continually strengthen yourself with your awareness that Hashem is king and be prepared to serve him with temimus.
The Rambam (Hilchos Teshuvah 3:4) writes, "Although tekiyas shofar on Rosh Hashanah is a gezeiras hakasuv (a law, without a known reason), it is hinting to something. The shofar is saying מתרדמתכם הקיצו ונרדמים משנתכם ישנים עורו, "Awaken sleepers from your sleep..." A handwritten version of the Rambam states עורה twice: משנתכם ישנים עורו עורו. Perhaps the intention is that one should rouse himself again and again. If, after resolving to do teshuvah, he forgets his resolve, he should rouse himself a second time.
בראשית stands for ראשית-ב (two beginnings). This indicates that if one tried to change his ways once, and failed, ראשית-ב, start from the beginning again and try a second time. And if necessary, start a third time, and a fourth time, until you succeed.
Each week, Shabbos at Minchah, we begin to read the new parashah, but we don't finish it. We only read until Sheini. Monday and Thursday, we start from the beginning again, and we only read until Sheini. On Shabbos morning, we read the entire parashah. This indicates that one starts and fails, starts again, and fails. But if he keeps at it, he will eventually succeed.
The Teshuas Chein zy'a taught that in the Mussaf Shemonah Esrei of Rosh Chodesh, we say נתת לעמך חדשים ראשי, Hashem gave His nation the ability to start anew, מיד נפשם תשועת שונא, and when they do so, their souls are saved from the enemy, from the yetzer hara (see Succah 52).
The Rebbe of Lechovitz zy'a said that הארץ ואת השמים את אלקים ברא בראשית, the entire world was created for בראשית, for people who start anew and try again and again to change their ways.
