Nefesh, the lowest degree of the spiritual world, is like a baby who does not understand anything yet, does not know anything, but already exists at the expense of others due to the fact that his parents provide him with everything. Certainly when it comes out of the mother, the nursing period begins.
Everything he has not received during the nine months of his intrauterine spiritual development, he receives in the first two years of life, the period of spiritual nursing.
This is a very interesting period because everything a person could not develop in our world, at our level, rises together with him to the world of Assiya, to a higher level. There he will receive this development in the form of milk.
Instead of receiving it at our level in the form of blood (a common circulation with the mother), he receives it there in the form of spiritual light.
In our world, the power that is developing a person is called “blood” since our world is inanimate; blood in Hebrew is “Dam” from the word “Domem,” “inanimate.” In the spiritual world, the power of light is called “Halav,” “milk,” because it acquires a white quality, the quality of bestowal.
