Kislev 13

My father said: Chassidus changes what exists, and uncovers the essence-character. The essence-character of the Jewish person is beyond estimation and assessment, for he is a part of (G-d's) Essence, and whoever lays hold of a part of The Essence is as though he lays hold of it all. Just as The Essence is unlimited, so is the part unlimited. This is similar to tzitzit being "on the corner"1 - i.e. "of the same material as the corner"2 of the garment. (The existence of the soul as an entity discrete from G-d's Essence) is only because G-d3 created the soul to be a created being; and Chassidus reveals the essence-character (of the soul).
