Chasidut к Авот 3:5

Regarding the verse (Vayikra 25:55) “The Children of Israel are servants to Me; they are my servants…” My claim came before [any other claim]. This is still true today, for according to the level at which one accepts the yoke of Heaven, enslavement to governments is removed, as our sages have taught (Avot 3:5), “One who accepts the yoke of Torah, has the yoke of government removed.” There are also roles of servant and child… [The roles of servant and child] parallel the aspects of Torah and commandments, for one who engages in Torah [as a child of G-d] is free. (Avot 6:2) However, everyone must accept the yoke of Heaven and of commandments upon themselves [as a servant]. This is the meaning of the verse, “They are My servants”, as it is written “Israel, in whom I am glorified.” (Isaiah 49:3) It is glorious for G-d when Israel accepts servitude to Him, despite being His children. It is not only praise of Israel, but it is also true testimony to the Creator… There are always levels of servant and child, servant and child, in that the greater one’s grasp of the secrets of the King [as G-d’s child], the more one lowers one’s self to accept the yoke of Heaven as a servant. Consequently, one merits to see and grasp, as a child, and then one returns to being a servant… In Nisan, we become free and receive the yoke of Heaven. All the days of the Sefirah, we are like servants, doing His will, until we achieve seven complete weeks, which is the oath we swore and in which we have stood since Mount Sinai. We then merit on Shavuot to receive the Torah, like children who search through the vaults of the king. However, we then return to being servants, which is Sukkot, when we return and repent on Rosh HaShanah and Yom Kippur, and accept the yoke of Heaven anew, which is the glory mentioned above, as the Holy One finds glory in them…Similarly, daily, one accepts the yoke of Heaven [as a servant] in the morning and thereby merits Torah [as a child] according to his level. And at night, one returns to accept the yoke of Heaven. And the level of the “second servant” is greater, as can be understood.
