Passover is a Jewish holiday. It commemorates the story of the Exodus, in which the ancient Israelites were freed from slavery in Egypt. Passover begins on the 15th day of the month of Nisan in the Jewish calendar, which is in spring in the Northern Hemisphere, and is celebrated for seven or eight days. It is one of the most widely observed Jewish holidays.
The Kabbalistic interpretation of Passover is that it's humanity's run for freedom. Freedom from what? From the clutches of ego.
Ego decided that humans will do away with Source, and they did. For six thousand years. So it is most befitting that during Passover, the method to connect to Source was revealed.
Now it is up to each individual to run for freedom, and connect.
