Chasidut do Izajasza 50:2

This is not the case with the hasidic mode of revelation, through which these words of the Zohar are almost self-explanatory, even according to our meager grasp. For all the chains and sefirot exist in Israel, and in point of fact all the supernal worlds emanated and were created and formed for the sake of being revealed in the Israelite person. It is for this reason that they were made in the image of a person.⁴¹⁸Rather than the human form imitating the supernal form of Adam Kadmon, the latter, in fact, reflects the former! Thus the Zohar says that Israel completes God’s faithfulness [or, belief in God; emunah] in the world. First, because they reveal His divinity in the world, as the Mikdash Melekh explains. But further, because they themselves—literally, they themselves!—actively do this, since in them exist all the worlds, sefirot, etc… “Israel is the completion of the Holy Name.” So too, the unifications which they perform and intend not only affect that which occurs Above, but also unify all the holiness inhering within them, until Atzilut. When they are in exile and descent, both physically and spiritually, their Holy Spirit is distant from their bodies and souls. This is the separation between Tiferet and Malkhut within them, and within all the worlds. This is not to say, God forbid, that it is totally distant from us, for it is with us even now. The lack is “Why, when I came, was no one there, Why when I called, would none respond?,⁴¹⁹Isaiah 50:2 no one whose spirit is aroused?”⁴²⁰The capacity and potential for unification remains alive; all that is needed is spiritual awakening and arousal to enact it. The essential point is that the person should be,⁴²¹That is, truly exist and live. and that means that his spirit should be aroused. He should not just say words of the prayers and perform the commandments, but rather his spirit should be aroused, for as we have already said, this is the essence of hasidism: the awakening[hitorerut].
