In the world of Yetzira (Formation), the aforementioned third level is dominant, which includes the incorporation of a small amount of the form of the will to receive. Therefore, when the soul descends and enters the world of Yetzira, acquiring that vessel, it leaves the spiritual level of neshama and is then called ruaḥ. On this level, its vessel is intermingled with a slight degree of opacity (ovyut) because of the small amount of will to receive that it contains. Nevertheless, it is still considered spiritual, as this amount of opacity is insufficient to separate it entirely from His essence to the extent that it can be called a body that exists in its own right.
