The armies of heavens ask each other about where the Holy One Blessed be He focuses his attention. They are told that his desire is to have unification with his vessels that are brokenhearted people. Nobody knows what is done with the prayer of the poor because the power of these prayers comes from the desires and the pain that brings the poor to tears and complaints to God. The Holy One Blessed be He accepts these prayers and they are poured in front of him. Because of that, all other prayers are delayed.
Moses made his prayers and was delayed several days because of the prayers of the poor. King David saw that the windows and the gates of heaven are ready to open for the prayer of the poor so he removed his royal clothes and sat on the ground as a poor person, saying his prayer;
“תְּפִלָּה לְדָוִד הַטֵּה יְהוָה אָזְנְךָ עֲנֵנִי כִּי עָנִי וְאֶבְיוֹן אָנִי.”
“A Prayer of David. Incline Your ear, O YHVH, and answer me; For I am poor and needy.”
God asked him; aren’t you a king and ruler over other great kings? Immediately King David change his prayer and said;
“שָׁמְרָה נַפְשִׁי כִּי חָסִיד אָנִי הוֹשַׁע עַבְדְּךָ אַתָּה אֱלֹהַי הַבּוֹטֵחַ אֵלֶיךָ.”
“Preserve my soul, for I am a godly man; O You my God, save Your servant who trusts in You.”
He left out the words ‘poor and needy’ and used ‘godly’ (חסיד, Chassid) and ‘your servant’.
This teaches us that King David expressed himself in his prayers as a poor and also as a faithful servant of God.
Our prayers should be honest and from the heart, so our ‘demands’ would come closer to God. The pain of a broken heart represents a lack of Light and tears express the desire to receive the Light from the upper levels. It’s like a strong vacuum that draws the ‘attention’ of God.
Malchut doesn’t have the light of its own and that ‘empty’ vessel has the greatest desire for the light.
