Reb Yechezkel of Kuzmir zt’l lit his Chanukah lecht with his family and wouldn’t permit his chassidim to watch him perform this mitzvah. He said this is alluded to in the Chazal (Bava Basra 57:), which says, “It is forbidden to look at women when they are washing.” He said that "women" represent Jewish souls, and "washing" refers to when a tzaddik washes the Jewish souls from their blemishes. When Rebbe Yechezkel of Kuzmir would light the Chanukah lecht, he purified and washed the souls of the Jewish nation, and Chazal said, "It is forbidden to look" when this washing takes place.
Meir Einei Chachamim (12:2) writes, “Believe with emunah sheleimah that when you stand to light Chanukah lecht, all the sparks of your neshamah and the neshamos of your father and grandfathers, all the way up to Adam HaRishon are standing there with you. This applies to every Yid who lights Chanukah lecht. The neshamos hope that perhaps with your hislahavus and inspiration by the Chanukah lecht, they will merit a rectification and reach their origin and source.”
