Answer: According to the degree of connection between us, we can measure our place on the spiritual ladder, which is called Jacob’s Ladder, how we rise from our world in 125 levels, through five worlds until we attain Olam Ein Sof.
In every world, there are five Partzufim, in every Partzuf, there are five Sefirot, and in sum there are 125 levels (5 x 5 x 5). The difference between all of these levels is greater and greater connection and union between us.
This union always is realized in a group of ten (Minyan). If we connect correctly, we nullify ourselves, and then we begin to feel the connection between us, as well as a new spiritual force that is discovered in our connection.
The more we connect, the more each one of us feels how he rises on the ladder of spiritual levels, until reaching its end.
