Answer: In order to hear the upper you have to connect. Malchut of Atzilut is called Knesset Israel (the assembly of Israel) since it assembles all those who yearn “straight to the Creator”-Yashar-El (Israel).
Then they all connect in Malchut of Atzilut and then Malchut of Atzilut raises a prayer (MAN) up to Zeir Anpin, and together rises as with a big brother to father and mother (upper AA). This is what happens in all the levels until the world of Ein Sof (Infinity).
So the connection with the upper is only possible if I am connected with those who are equal to me. First we have to create an “assembly,” a connection, a gathering of friends. The main thing is to annul yourself at least before one person, and by that you are ready for the connection with the other.
The term “upper” exists only inside us. Who is a teacher—“rav” (great in Hebrew)? He exists only in the center of the group. If you think about a teacher outside the center of the group, he is not called “rav” but simply a teacher, a scientist, or a wise man. He doesn’t become a guide.
A guide is someone who shows you the way. It is someone who is in the center of the group and who says, “You all have to connect around this center.”
