Before going to the memorial meeting each of us should not only have cleansed his house, but also the inner being, having thrown away his "old leaven", our old being.

Let the coming chag not be polluted by old yeast, but that you observe the Festival of Unleavened Bread like the Most High wants us to remember the exodus of the Bnei Yisroel.
