I love the Ann Ulanov's (Jungian analyst, Professor of Psychiatry & religion) articulation of Abraxis (@2:09) in her incredible encapsulation of Jung's Red Book. Her talk begins at 1:43 https://www.youtube.com/watch?v=Oy-x7BLlBYg

This is also available in printed version here https://www.jstor.org/stable/10.1525/jung.2011.5.3.54

Abraxis eludes any easy definition, but her talk brought it alive for me.
