This week we Are cleaning for Pesach. Searching for chametz(anything leavened or fermented made with wheat,oat, barely,spelt or rye). Spiritually chametz represents our EGO, which makes us leavened with arrogance. That is why we eat Matzah for eight days so we can become flat and humble through the rest of the year. And when you get rid of your EGO aka Selfishness that is when we become really free.
