Rebbetzin Freida was the daughter of the Alter Rebbe, R. Schneur Zalman of Liadi. She was especially dear to her illustrious father, and he would frequently deliver chassidic discourses specifically for her. In fact, when her brother R. DovBer, who later became the Mitteler Rebbe, wanted to hear Chassidut, he would sometimes ask her to make a request, whereupon he would hide and listen.
Rebbetzin Freida passed away a few months after her father, and was interred in Haditch, Ukraine, immediately adjacent to R. Schneur Zalman.
Yom Kippur is described in many ways. One very poignant description is that it is “once in a year.”
You see, the human soul is also described in many ways, with five different names, each describing a deeper level of her being. The fifth, deepest level is called yechidah, which means “one and unique.” Yechidah is the soul as she is fused and one with her Creator, so that the two are an inseparable whole.
Yom Kippur is the day that the essential bond of yechidah shines within the time and space in our world.
Meaning that once in a year, the One Above unites with the essential oneness of the soul here below within each one of us.
All else falls away.
