A collective prayer that does not remain unanswered is a prayer “for the society,” a request to gather all of the souls that yearn for the Creator into one soul of Adam. This prayer is immediately accepted by the Creator (the system of Upper Forces of the World of Infinity, where everything is unchanging and perfect) because it aspires for perfection.
If people all over the world feel the need to know the Upper Force and unite their desires, then they do not feel separated by continents because they are in fact in a common “range” of spirituality. They exist in one spiritual plane without feeling geographical distances in our world but by feeling closeness in spirituality. They do not know and cannot explain how this happens, but their aspirations toward one goal pull and unite them inside a common spiritual field.
In this way, they all enter “Knesset Israel” (unity of those who aspire for the Creator, the quality of bestowal). “Knesset” (assembly, gathering) is the place where we all unite as one man, meaning Malchut of the World of Atzilut. Similarly, “Israel” (Yashar-El – straight to the Creator) signifies the souls who aspire toward one goal. Consequently, they become one assembly called Knesset Israel, the gathering of the souls who desire to attain the Creator.
They feel as one whole connected by one desire, one goal, and one purpose. Thus, there is a return to one body of the collective soul, as it was before the breaking of the Kelim (the vessels, desires) and the emergence of this imaginary corrupted world, perceived as our present reality.
