Here's another look at the trickster. The double or form of ka is a mercurial fool or trickster spirit at times. This is the psychological form of impulsive behaviour.

This spirit is as much a guide to our heroic nature as it is too our foolhardiness. As it does not die with the body or undergo judgement as we do. It is free as of our death, thus it has no fear.

This is the form we must control to attain balance and perhaps get inklings of our divine or semi divine soul.
