the Name of this tradition is “SHETAUT NETER” meaning “Hidden Divinity” or that the divinity is hidden. In other words the nature of the Divine and indeed, of Creation and the origins of the soul is a “Mystery” and that is why it is refereed to as “Egyptian Mysteries”. Where is it hidden? there is the question that the Mystery School seeks to answer and that is the goal of all initiates.
Now, once the teaching is followed then certain answers are revealed and certain insights are gained by the individual and thus the mysteries are discovered. From the outside they are mysteries just as the knowledge of any discipline in life (doctor, lawyer, engineer, chemist, etc.) is a mystery until it is taught and understood.
The task of discovering the mysteries is the work and goal of every aspirant and the goal of the mystery school is to help that process.
