To return to the main theme: The world of Nekudim is an overall category that produces these two kinds of roots with all their offshoots: the lights governing Atzilut, Beriyah, Yetzirah and Asiyah are the offshoots of one root, and the separate creations themselves are the offshoot of a different root. This will help explain what you will always hear us saying, that everything was made through the process of selection and purification (בירורים, birurim) of the Primordial Kings.
For this is how the lights emerge from this general category, just as do the separate creations. However, it is only in respect of the overall goal of turning evil back to good that all are equal, as stated above. Although we say that Nekudim is a category, it must be understood as being more than a category but rather as a single material or substance that includes all that comes after it.
