English Notes: 

There is no English term that conveys the meaning of the German term Wesen, that is why the same word is used: Wesen

English Description: 

A Wesen is an independently existing life form with its own individuality and personality in an impulse-based, instinct-based or conscious consciousness-form with evolution-possibilities that are specifically directed towards everything, and with its own physical, psychical (relating to the psyche), conscious, part-conscious, unconscious, impulse- or instinct-based development-forms (human being, animal, creature and plants).
