An important lesson we learn from Yered (which means to descend) in our approach to prayer and Divine service is understanding the role of humility. The Chazan (the prayer leader) is called "Yored Lifnei HaTeivah," one who descends in front of the Ark (It is worth noting that early mystics were called Yordei Merkabah, those that descend [to reach] the [Divine] Chariot). The place where the Chazan stands would literally be lower than the rest of the synagogue, and Jewish law forbids praying from a physically elevated place (with certain exceptions). The rationale for all this is because prayer has to come from a place of humility, "MiMa'amakim Karaticha Hashem," one must call out Hashem from the depths, literally. As mentioned last week, it is essential to "Know Before Whom You Stand."
