Pray for the Shechinah's Lack, and Your Own Is Filled
Citing his grandfather the Baal Shem Tov, our personal lacks mirror the Shechinah's lack, and prayer should aim at filling that first.
On Yitzchak praying opposite his wife, the Degel records a deep teaching of his grandfather, the Baal Shem Tov. Everything flows into our world from the Shechinah, so whatever a person lacks reflects a lack, so to speak, in the Shechinah. Our prayers should therefore ask that the Shechinah's lack be filled, and in that very way our own will be repaired. This is why the Zohar calls tzaddikim the messengers of the Matronisa, the Shechinah: through their own want they feel that of the Shechinah and join her in a complete union. The Degel then links this to the idea of daas, which allows true union, and to the letters of the name Adni, with which he reads Yitzchak's prayer.

When you notice something missing in your life, a worry, a need, a longing, let it widen your prayer rather than shrink it. Today, when you daven or say a few words to Hashem, begin with a short request for the world: for the Shechinah to dwell among Jews, for peace, for those who are suffering. Then add your own need as a part of that larger picture. Many people find that their own concern feels lighter once it is held inside something bigger.
