Answer: A spiritual Partzuf is formed only as a result of our connection with one another. There is no person who would have his own individual spiritual Partzuf. A Partzuf is a measure of our connection, and it appears only between us.
A spiritual degree is a measure of bestowal. However, for this purpose I have to bestow to someone. Let’s say I bestow to you. It means that I am heading this bestowal to you, I am its head (Rosh). I attach your desires to myself in order to fulfill them. This way the head and the body of my soul are formed (Rosh and Guf). Together, they are called “Partzuf.”
