If we take the alchemical maxim "As Above, So Below" seriously, we should be able to find correlations between the structure of the psyche and other natural systems. This should also apply for the domain we call the shadow. In my own work I have extrapolated the biological relationship profile we call parasitism onto the shadow of the psyche and found great similarities. The active component of the shadow can be seen in terms of parasitic relationships. Here is a video where I lay out this thesis in a more or less concise manner.
