Chasidut su Isaia 66:22

This is why love of Israel is so great a thing. According to the Besht’s path, and the result of his holy path, all is divine light, and the Israelite illumines from God’s essence, and all worlds are completed through him. How, then, would it be possible to love God if one does not love, with a complete love, Israel, in whom is the light of God’s essence? One must love all of the Israelite, to endeavor to see to his bodily needs, since he is, from head to toe, inside and outside, a piece of the holy of holies. In the writings of my revered and holy father, it says that one must even give over one’s life for the sake of Israel, and that such a gesture reveals one’s love and connection to God. It is like when the servant of a king gives over his life for the sake of the prince, the king sees just how connected the servant feels, that he is willing to do so not only for the king himself but even for his son. [Note: See Likutei Torah, end of Song on Songs,³³⁸Discourse by R. Shneur Zalman of Liadi on Song of Songs. on the verse “as with the new heavens,”³³⁹See Isaiah 66:22. he says “ The souls which descended down to this world...drawn down an influx of light in Eden from God’s essence...for Israel draws down from the sense of ‘and You are holy’ to ‘and Your name is holy.” For “Your name” refers to the vessels which develop in all the worlds, and draw from “You are holy” in the sense of God’s essence.]
