Likutei Moharan 33:7/ליקוטי מוהר"ן ל״ג:ז׳

17. Thus every person, each one commensurate with his aspect, is capable of having a taste of the light of the love that is in Daat even now, within the days. This is when he binds his heart to his daat. For each and every Jew knows in a general sense that there is a God. But the wicked are controlled by their hearts, and the attributes and days are encompassed in the heart. As our Sages taught: The Compassionate One wants the heart (Zohar II, 162b) ; and, provided he directs his heart to Heaven (Berakhot 5b). For the heart is the essence of the attributes.

2We see, therefore, that when a person binds his heart to his daat, he knows in a general sense that there is a God whose “Glory fills the whole world” and he also knows the Torah’s knowledge. Thus, when he subjugates his heart to this daat which he has—i.e., he has control of his heart—then the attributes in his heart are encompassed in his daat and so the attributes receive the light of the love that is in Daat. He thus sees and grasps the hidden light commensurate with his aspect. In other words, when he subjugates his heart to Daat, the heart, which is the root of the attributes, receives the tzaddikim and Torah that were hidden and concealed from him until now. And he receives the light of the love that is in Daat. This is the love between the Holy One and Israel that existed in potential prior to Creation.
