And with this we can understand the concept of Mitzrayim of Kedusha, that constraint is the ‘narrowness of the neck’ which facilitates a possibility of Middohs from Mochin - even in Kedusha - so that just as there is a narrowness of the neck in a person’s body below, so too is there a narrowness (Mitzrayim) in the ‘Supernal Man’, because man is called Odom due to being similar to the Supernal Man.
And this concept in holiness (which is the disruption and the reduction) is a good thing because it brings about the revelation and the creation of Middohs to the extent that it is specifically because in this manner it brings forth the action.
So now according to all of the above we can understand the concept of ‘leaving’ the Mitzrayim of holiness; for Mitzrayim represents the ‘narrowing of the neck’ which is the contraction and separation between the mind and the heart.
