Continuing the compare-and-contrast analysis of יציאת מצרים vis-à-vis the final גאולה, the רבי explains the quality of יציאת מצרים, which is why we compare to it the final גאולה:

Although יציאת מצרים was no as great in level as the final גאולה will be, it was the first גאולה, and therefore the beginning of the process for all subsequent גאולות.

Bringing מתן תורה into the picture, we see the full sequence of the process, beginning with יציאת מצרים, continuing with מתן תורה - which then began a new step in the process - and finishing with the final גאולה.

This explains why we use the plural term, "כימי צאתך", because every day is continuing the process of liberation that began at יציאת מצרים!

The רבי invites us to break free of the new boundaries that each day brings. With such a lifestyle, we live a life of constant freedom!
