It is the same in the case of man here below: the soul (neshamah) builds the body through one general power contained within it. This is the “Likeness of Man”, and this is the name MaH we have mentioned. For this must also exist in man here below in accordance with the secret of the “irrigation of the tree”. It is from this that the entire structure emerges, and this is what experiences all the feelings and sensations of the different parts of the body, and it is from this power that their interrelationship derives. It is the spirit (ruach) itself that is affected and activated in the place where it dwells.
How the Neshamah Builds the Body It Inhabits
