Musar do Rodzaju 1:31

And our Rabbis, may their memory be blessed, said (Avot 3:1), "Keep your eye on three things, and you will not come to sin [...] From where did you come? From a putrid drop. And to where are you going? To a place of dust, worms, and maggots. And before whom are you destined to give an account and a reckoning? Before the King of kings, the Holy One, blessed be He." The explanation of the content is [that] when you think of from where you came, your spirit will be humbled and you will hate pride. And when you remember where you are going, you will scorn the world, recognize that its superfluous luxuries are nothing and only be involved with it for the service of the Creator, may He be blessed. And when you put into your heart in front of whom you will be giving a reckoning, fear of the Heavens will be upon you. And our Rabbis, may their memory be blessed, said (Genesis Rabbah 9:5), "'And God saw all that He had made, and found it very good' (Genesis 1:31) - this ('very good') is death." For even death is good, so as to subdue spirits, that there be fear of God upon the hearts and that they not make this world into the main one. But there are people that do not give time to their souls to understand their ends, because of their preoccupation with acquisitions of the world - like the matter that is stated (Job 4:21), "Their cord is moved, and they die, and not with wisdom." Its explanation is, is not their cord (yeteram, which can also be understood as their excess or advantage) - their money - moved from them in their move; for behold they have no benefit from it [when they die], yet it lost much good for them. For it caused them to die without wisdom, as they did not show wisdom to understand their end, to rectify their souls and prepare provisions for their journey, - like the matter that is stated, (Deuteronomy 32:29), "Were they wise, they would think upon this, gain insight into their future."

The number six in the six hundred thousand reflects the six directions in which the forces of the emanation תפארת radiate their influence. Israel, as the root cause and purpose of the creative process, acquired so much importance that each Israelite had to be individually counted. The number six and multiples thereof are so significant that the Torah was given on the sixth day of Sivan (or according to some on the seventh day of Sivan). In either event, the date alludes to a similar concept. The difference is only whether we consider the emanation מלכות in which the process which had taken place during the prior six emanations became visible, as included in the symbolism. Our sages, in commenting on the word יום הששי in Genesis 1,31 have described the six days of creation as a period during which all the matter which G–d created remained in a state of suspended animation until, with the advent of the giving of the Torah and its acceptance by 600,000 Israelites, the universe really qualified to become enduring (Shabbat 88). When Moses appeared in the Celestial Regions in order to take the Torah to the Jewish people and the angels challenged him, G–d told Moses to take hold of His throne, as reported in Shabbat 88. This was possible only because by acceptance of the Torah (i.e. the Ten Commandments) by the Jewish people which made them carriers of G–d's מרכבה. Israel itself had become G–d's throne. When the Torah speaks about כי תשא את ראש בני ישראל, "When you elevate the Children of Israel,” the Torah wishes to tell us that the "counting" is proof of the Jewish people having been elevated spiritually.

Creation i.e. בריאה, is divided into three "days." On the first "day," G–d created; on the second "day," He ensured that what He had created would endure. This was the day on which the Torah was given to the Jewish people, when the earth was both frightened and reassured in turn. G–d had added the letter ה to the Torah's report that "it was evening it was morning יום הששי, "the sixth day." [an allusion to Israel having to accept the Torah so that earth's continued existence would be assured based on Midrashim we quoted elsewhere. Ed.] יום הששי, "The sixth day," refers to the 6th of Sivan, the date on which the Jewish people accepted the Torah. G–d had threatened that non-acceptance would result in the world again being turned into Tohu (compare Shabbat 88). The third "day" of creation is the day when G–d's handiwork will undergo a complete rejuvenation in the messianic future, seeing that G–d's original handiwork had been largely ruined through Adam's sin (and that of his descendants). At that time the verse ישמח ה' במעשיו, "G–d will rejoice in His works," will be fulfilled (Psalms 104,31, the word ישמח having the same letters as the word משיח).
