Question: How can I attach the desires of others to myself in order to attain a common prayer?
Answer: You have to understand that all the corrections happen inside our common sphere, which is called a “place.”
If my thoughts are anywhere outside of this common place, it means I am outside of Malchut of the World of Atzilut, outside of Malchut of the World of Infinity, outside of the group, the “place” where the Creator is revealed (the Creator is called a “place”). This means I am outside of reality.
The place where He is revealed is called reality. This world, where the Creator is concealed, is not considered to be actually existent. All of the spiritual reality is revealed inside of our common Kli, vessel, or desire.
