Answer: Building a spiritual Partzuf between us means to want to connect between us with complete and absolute bestowal.
The part of all of our desires that is ready for mutual connection is called the Toch (trunk) of the Partzuf.
Intentions within this Partzuf directed towards bestowal as a support for discovering the Creator, to give Him contentment is called the Rosh (head) of the Partzuf.
When you begin to connect correctly and seriously, you will feel a lack of bestowal towards the Creator and the conditions for this will appear.
