Malachim are nivdal (separate) with a self identity. Sefiros are netiyos, lights of Hashem with no self identity, but are bittul to the Aibishter. Havaye and Elokim like right and left hand of a person. A Moshol M’chuvan is an exact moshol from the Torah chosen by the Rebbeim that conforms to the nimshal in every detail. A moshol bilti m’chuvan is an inexact moshol that can come from the world at large that only conforms to the nimshal in certain aspects to illustrate certain points. Adam Hatachton (us) is a Moshol m’chuvan for Adam Haelyon (Atzilus) because the powers of the neshama come from the sefiros of Atzilus and are nishtalshel from them.
