Forty days before Purim, Breslov Chasidim have a tradition to cry out and pray: הַצִּילֵנִי מִקְלִפַּת הָמָן עֲמָלֵק וְזַכֵּנִי לִקְדֻשַׁת מָרְדְּכַי וְאֶסְתֵּר Save me from the impurity of Haman and Amalek and purify me to the holiness of Mordechai and Esther. Haman, a descendant of Amalek, represents the disconnect of mind and heart.
The sanctity of Mordechai and Esther is the deep connection between our intellect and emotions. In the video, as the heart fills up with blood, which represents vitality, it gradually transforms from a heart of stone to a heart of flesh.
When we learned of this custom, we were moved to write a melody to go along with the prayer.
