The prayer of the poor breaks through all gates and openings on the way up to enter and stands in front of the Holy One Blessed Be He.
” וְהָיָה כִּי יִצְעַק אֵלַי וְשָׁמַעְתִּי כִּי חַנּוּן אָנִי ”
“When they cry out to me, I will hear, for I am compassionate.”
“אִם עַנֵּה תְעַנֶּה אֹתוֹ כִּי אִם צָעֹק יִצְעַק אֵלַי שָׁמֹעַ אֶשְׁמַע צַעֲקָתוֹ”
“”If you afflict him at all, and if he does cry out to Me, I will surely hear his cry;”
Rabbi Elazar says that the prayers of Tzadikim, are joy and beautification for Malchut. When it ascends to heaven, the Holy One Blessed Be he, welcomes it with love. He awaits the prayers of the righteous because they know how to please their master.
Jacobs prayer was proper
“וַיֹּאמֶר יַעֲקֹב אֱלֹהֵי אָבִי אַבְרָהָם וֵאלֹהֵי אָבִי יִצְחָק יְהוָה הָאֹמֵר אֵלַי שׁוּב לְאַרְצְךָ וּלְמוֹלַדְתְּךָ וְאֵיטִיבָה עִמָּךְ”
“Jacob said, “O God of my father Abraham and God of my father Isaac, O YHVH, who said to me, ‘Return to your country and to your relatives, and I will do you good’”
Jacob did the proper connection to elevate his prayers to the highest level. He connected the Right with ‘God of my father Abraham’ then the Left with ‘God of my father Isaac’ then to the center, himself with ‘O YHVH, who said to me’. After establishing the connection to the Tree of Life, Jacob could raise God’s promise ‘I will do you good’.
While the prayers of the poor can go all the way up, be heard and receive fulfillment, the prayers of the Tzadikim have special quality, enhanced by pure consciousness and desire to please God. The Tzadikim don’t think of themselves and their prayers are always to draw light to the world, for the benefits of all.
