The point of it all is still that one word: nafshatana. Our souls. Note that it's plural. No one is doing this alone, without a net. That is why we do all this, why we sing and pray and stand together in shul and support each other in our turning and returning. On erev Yom Kippur this Friday night (also erev Shabbat, making for one heck of a sabbath if you ask me), we will hold up each other's souls in support, humility and love. And THAT is what I have come to understand that Kol Nidre is really about.
If you are preparing for Yom Kippur, G'mar chatimah tovah -- may you be sealed in the book of life for a good year.
