Q: There are many questions about the connection between the spiritual world and our own. You say different things in different places. If there is no connection between the two worlds, then how is spirituality connected with externally observed Mitzvot?
A: You are, indeed, quite right. Only the Mitzvot performed inside connect man with the Creator. However, observing Mitzvot externally also becomes a means for connection. Everything comes through the soul. A Mitzva is a spiritual act of giving to the Creator, which likens man to Him. External action has no such effect.
The Creator doesn’t put on Tefillin made of animal skin. His action is the Light of GarDeHochma in Gadlut of Zeir Anpin, which is defined as Tefillin. That is what one must attain.
