Until we are willing to take on the suffering of those who are oppressed as if it is our own, we will never experience true empathy and true compassion. To help us begin to embrace that experience, we eat the matzah with the maror, a seasoning reflecting the bitterness of those who lack freedom.

בָּרוּךְ אַתָּה יי אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם, אֲשֶׁר קִדְּשָנוּ בְּמִצְוֹתָיו וְצִוָּנוּ עַל אֲכִילַת מָרוֹר

Baruch Atah Adonai Eloheinu Melech ha’olam, asher kidshanu bimitzvotav vitzivanu al achilat maror.

Blessed are you, Adonai, Sovereign of Existence, who hallows our lives through commandments
Who has commanded us regarding the eating of  maror.

Everyone eats a bite of the matzah with horseradish.
