Answer: None. We come from the broken vessel of Adam, and therefore we only need to unite with each other. There is no need to philosophize. I do not know how I need to connect, with whom, by what properties, etc. I only have to expose myself to the influence of the upper Light.
I cannot be smarter than the upper Light, but can only cause its impact so that it corrects me. I cannot be above the point of my correction, and so I only ask. Everything is achieved only by prayer.
